Lots of people talk and worry about vinyl records wearing out, but finally here is a controlled, long-term experiment to test how much audible wear actually happens to records played in real-world conditions on a variety of turntables. I highly suggest a quiet listening environment and good pair of speakers or headphones to observe the results. However, the main takeaway from this test is something that experts have already known for the past 75 years: dust, dirt, scratches, fingerprints, improper storage, and a worn stylus are the real enemies of vinyl record life, not the kind of turntable you use. Do your best to avoid those perils, and your records will provide a lifetime of enjoyment, even when played on inexpensive equipment. FYI: The records I tested are slightly transparent when held up to a bright light, indicating they were made with a vinyl formulation which used dye instead of carbon black; these records (marketed under various names such as "Super Vinyl", "Quiex", "UHQR", etc.) are known for their very low surface noise and anti-static properties, but sources differ on whether they last longer or actually wear out more quickly than conventional vinyl. Unedited video of playing a portion of the record on the Quasar 50 more times, for a total of 100 plays at the end of the test: ua-cam.com/video/qee4wp9Swto/v-deo.html Lossless recordings of all four records used in the test (both the entire album side played with the Stanton 681EEE cartridge, and the brief samples I played using the Shure M75): drive.google.com/drive/folders/1UscEjplMoS6l-Rw3RAnWlDdOY06-GhID (Yes, the unplayed record actually has more pops & clicks than the ones that were played 50 times. Maybe it has some dirt in the grooves, and/or was a noisier pressing than the others. None of the LPs came with inner sleeves -- they just put the record directly in the cardboard jacket.) Time flow: 0:00 Introduction 1:17 The equipment 2:55 The records 5:35 How many times? 7:37 How often? 9:58 The test 13:34 The results 17:08 Analysis 22:31 Stress test 26:12 Conclusion p.s. I found the obituary for the father of the group, which says the Marcus Family Singers were formed in 1974 and were active for seven years, and recorded two albums: www.petersonbrothers.com/obituaries/calvin-marcus Also I looked up the songs on the album in the copyright database and several of them were written in 1980, so the album is probably from 1980 or 1981. You can listen to the full album here: ua-cam.com/video/C1jJxwdpX60/v-deo.html
When I was a child, I had an LP of "Help" by The Beatles that played it so many times that it ended actually worn out. The record player was a suitcase Denky turntable.
06:40 - Say what you will about RCA, the fact that they implied (with a straight face no less!) that an audiophile will "show off his sound system to friends" more times than actually listening to the records themselves is both extremely hilarious and fairly spot-on.
I feel one of the reasons for this is that audiophiles play those songs so often for friends that they tire of them and do not want to listen to them when alone. I guess it's too much of a good thing. ~
Honestly it’s a minor miracle in and of itself that these records are playable at all. If they were handed down at a church (which is implied by their quantity) they would be either played to oblivion by fundies or tossed into the most forgotten corner of the house. Maybe the distributor themselves gave them/sold them to the thrift store?
@@someguitardude8462huh.. ngl man that is a pretty legit good point lol fwiw I can easily see it being one of those two vs in between for the lack of dust and yet still warpage in some of them.
Your channel is the only channel that uploads this sort of content. Most channels cater to the audiophile foolery but this channel debunks it. Keep it up!
I am subscribed to both of those channels and love them. They showcase a lot of interesting things but I don't believe they've ever debunked any of the audiophile nonsense that goes on in the world today.
@@azjames8789 Techmoan has debunked audiophile nonsense. For example there was the video where some company sold a device to shave the edges off compact discs. They claimed this increased fidelity. On a CD.
back in the sixties i left a party and returned in the morning to find my brand new Roling Stones album had been left on repeat overnight for several hours, the record showed no signs of wear at all and fifty years later after countless plays it still sounds fantastic on modern equipment.
I agree, we all buy used records and play them on our high end stereo systems and they sound great. You can imagine those same albums were played on all kinds of cheap systems in the past. Stop worrying about the records and enjoy the music you love.
If it was a pressing of "Hot Rocks" I could never find one that didn't have flaws. They came from the factory with flaws, and it always sounded like massive record groove wear.
Man, you just stuffed a whole bunch of vinyl snobs in a place they deserve. This test deserves 1 million views min. Great job with the test. Data proud!
How so? I think "vinyl snobs" are all well aware that with a good table and good cart you can play your vinyl records without fear of harming them. Matter of fact, most of them preach this when folks tend to worry about it.
@@wymotome Vinyl snobs are those folks that came up with utter bs like Vinyl rest, for 24 HOURS. Silly Or that it is time to replace your vinyl after any number of plays. You are correct that those that say, keep your gear clean are spot on. This well thought out and logically performed test put to rest that snake oil statements made by folks generally selling pollihollow thermofuzz fake remedies, are shown to be disingenuous.
Did he ? This guy has his own bias, which is is that he thinks cheap plastic, junk, chinese made crap is okay to play precious record collection on. His whole channel is him being thrifty... or perhaps a hoarder, and playing old beat up crap I would NEVER touch. You guys wanna use crossleys and cheap ceramic carts to play your stuf back fine, but don't start this proselytizing crap. I literally laughed out loud when. he represented some obviously worn, aged, second hand stuff as "high end gear". No. Even his technics is still some belt driven thing with microphonics in the case. he didn't even use modern, new records, trotting out some corny religious stuff. Guy probably listens to the smothers brothers. I imagine his fan base is a bunch of old middle aged men that weren't successful in life and can't afford anything good and so get away with grabbing this kinda junk from the salvation army and trying to represent it as good gear.
I appreciate the fact that you have seemingly gone out of your way to be reasonable with this test. The music selected was done for the purpose of matching all of them up, nothing to do with what sort of music whatsoever. You maintained a regimen of playing them according to a schedule. Kudos to your dedication to getting trustworthy results.
Chrysler came out with an under dash record player for your car that played 45 RPM records. I'll bet it didn't take very long to get some record groove wear on those! And then remember those little cars and trucks that would drive around and round on your record and play it while it drove?
This is exactly what the vinyl community needs right now! People are being shamed to buy expensive equipment right from the get go, and treating vinyl like an extremely delicate form of music consumption, when the thing that greatly impacts your listening experience is dust! Congratulations on this lovely video, keep up with the great work man!
Yes, I was gifted one of those little suitcase players by my daughter. A friend immediately commented on my photo telling me to dump it and sped 300 on a 'good' player as I'll really damage my records. I ignored him and 6 years later im still using it with no issues or damage.vinyl snobs suck.
My family's had many records since the 60s, a lot of them have been played countless times and they are more than 50 years old, but they've always been taken good care of and they've always been played with high quality cartridges with good condition stylus, and many of them still sound awesome.
I've been following your channel for almost 10 years and let me tell you I believe you. You always achieve a great sound on your videos and I started to collect vinyl because of them.
Ehhhh... I *distinctly* remember hearing severe groove wear out of jukeboxes from time to time. Obviously dependent on a number of factors, but I'm willing to bet that the tracking forces on most of those machines was brutal. I loved watching the fancy automatic changing and playback mechanisms when they had windows, but they always looked like the tonearm was being absolutely slammed onto the record.
@@koozmusic Early ones playing mono records maybe, but the ROWE -AMI juke boxes played at very low pressures, as did NSM's and late Rock-ola's. I still have singles played on my ROWE-AMI that used an ortofon om10, and they're perfect. Rock-ola fitted the ACCU-TRAC tonearm to boxes in the 70's onward which was specifically designed for the geometry of a 7 inch record to minimise record wear.
@@analoglooney Hmm, interesting! The OM10 would definitely fall into the hi-fi category, for sure. Perhaps it was just the industrial-looking tonearm and deliberate, mechanical movement of it all that made me think they were rough on records. Then again, these are memories from the 80's and early 90s and I was a child. My dad had a very nice turntable though and taught me how to properly treat his equipment and records at only like 5-6 years old. While I found them infinitely cool, jukeboxes always appeared to handle them in a barbaric way to me. 😬
@@koozmusic LOL, yes they did look very crude and I didn't care much for the SEEBURG and early Wurlitzers. If you're ever out buying 45's you can always tell if they have been played on a Rock-ola. As the records revolve in the carousel they are kept from falling out by a metal band that passes underneath them. This eventually wears a slot in the edge of the records, especially the ones that aren't played a lot. The vendors didn't care as by the time it happened, no-one was playing the record anymore as they were bored with it! The computer controlled ROWE-AMI-s of the 80's also had jewelled arm bearings. Amazing for a juke.
You give such an objective take. I feel like trying to enter into the hobby is so hard because of the amount of purity test and audiophiles making this seem like you need a budget of at least 2000 to even start. You give real advice that doesn't sugar coat, but also doesn't demonize
Those folks fail to understand that telling people, "You're too broke to engage in this hobby" will never, ever get a person into vinyl listening. Get someone encouraged and started on simple equipment, tell them how to use the cheaper equipment to their advantage, and watch them work their way up! All this special noise equipment is hard to understand, and you have to take it in small portions.
I like that you call out people who waste time on forums, pontificating and arguing about how you should listen to music. They spend more time doing that instead of enjoying their music collection.
Would still feel better about playing an expensive record on a good quality table with a good cart vs. a cheapo Crosley. Even that Quasar is superior to a Crosley.
@@frankowalker4662 A Crosley was not tested and I have seen with my own eyes the "Crosley Crop Circles" that those turntables leave behind on newer vinyl. I would not make assumptions based on this video when it comes to Victrola and Crosley as they are different animals than that Quasar. And for the record, a lot of older vinyl was superior to the newer stuff. I'd like to see the test redone with a few modern "clearance" albums from the local Target.
@@wymotome Good point. I've got one of the UK versions of Crosley. (same design, different brand). But I only ever play my 1960's-1980's, (already scratched), records on it. My main deck is a Numark TT 1625 with an Audio Technica cartridge.
That's the problem buying second-hand records. you just don't know how they are going to sound even If they look mint they could be full of dirt and dust and permanently damaged by a worn stylus it's pot luck .
THANK YOU for putting another nail in the coffin of the whole "let the vinyl relax" malarkey! I'm not sure why some people in the industry thought it was appropriate to anthropomorphize vinyl records, but it's borderline crazy IMO, especially without data to back up the claim. Much like you, I've found that simply keeping the vinyl clean, and cleaning when necessary, to be the most surefire way to have a great listening experience.
There absolutely are polymer use-cases where you want to give the material time to recover. It is particularly the case with items that deform in use, giving them recovery time slows down polymer creep. EVA shoe soles are an example. I don't for a second think that records are susceptible to this. Hard PVC has very little creep to begin with. To be a little pedantic it's not PVC but according to Brydson's Plastics a blend with... i forgot, and doesn't matter, the mechanical properties are basically identical. To be kept in mind when you replay it, at least a few minutes have passed with material essentially at rest, after it was under impact for one tenthousandth of a second or so, just... different timescales to such a degree, that i don't see how a few more hours would help.
@@SianaGearz Remember the math question about which put more lb/sq in onto the floor, the elephant or the person wearing stiletto heels? The stylus radius being 0.2-0.3 mil for even a high quality stylus, and the amount of the groove wall vertically being contacted being on the order of 1 mil, the force pushing the stylus side to side is then being applied to an area of, ballpark, .0000006 inches square, or a multiplication factor of around 1.5 million. So 1.5 g = .0033 lb force, over 5000 psi. A handwave value for one reference's current recipe of 2/3PVA, 1/3 PVC mix in records is around 4000 psi tensile strength. (Not sure of exact grades mixed, but PVA is quite a bit softer and somewhat less crystalline than PVC.) Plus the stylus is applying a very significant thermal spike for those milliseconds. The surprise is maybe that the record surface /doesn't/ quickly degrade, though certainly the stylus is great at embedding dust and other particles into the groove walls. This test by VWestlife is reasonably scientific to the end result of "does it sound immediately different? No." and all of the commenters' related experiences with how poorly 45's in jukeboxes last are also a good bound to show that degradation is indeed happening from worst case high intensity repetition. I'd bet that 45's in radio stations, while probably kept clean, had even worse lives for the first week or two after the A-side hit the charts. FWIW I know from experience that playing a favorite vinyl album every afternoon after high school before the parents got home, on an ancient record player with a lot of tonearm weight, does indeed wipe out the grooves after maybe two hundred plays. I don't recall playing it multiple times in one day very often. But it certainly sounds like crap now, on a far better rig.
@@pault151 Yes you make a strong case that the stylus has a substantial impact on the groove surface and i agree. I don't know if tensile strength is a good metric since OK there would be tangential tensile impact, mostly compressive, but there is wear for sure. I also made a brainfart, the polymer used in records is a copolymer not a blend and yes polyvinyl acetate is softer. Brydson specifies 15% acetate used for vinyl records. It's ultimately not necessarily cut and dry, i mean, we all remember worn records, but was the gradual damage caused by the stylus contact, or was it caused by contamination such as surface dust, and how much of either? Dust can be substantially smaller than the stylus contact patch, which is bad, and it won't be as nicely shaped as the stylus. It's worse if you're tracking at 6g than at 1.5g for sure. The question here is "letting vinyl relax" and that it does nothing, because whether it relaxes for 3 minutes as you replay the same song over and over, or for 3 days, that's effectively both a very long time compared to the millisecond fractions the groove spends in contact with the stylus. So repeating the record constantly should induce the same wear as playing it for the same amount of time in total but letting it "rest" in between.
I imagine the Marcus Family would be proud that their unused recordings helped in this test, especially since we were all straining, listening so closely to the words and music (albeit for signs of damage 😁) Fantastic work!
I'm not sure. There is a lot of vibration and friction, and vinyl is a relatively soft material. Once every 24h-s is stupid, but playing a record over and over and over and over again, probably creates quite a lot of surface heat.
I studied materias technology at university. Yes it is absurd. It would be a problem only if it were played so fast that it could got the chance to heat up, but It won't heat up not even a little bit and even if it does, it would dissipate it immediately.
@@AnalogSins That would only be possible had the needle continuously ran the same exact groove for hours at a time. Literally impossible. Physics alone disproves this asinine theory of surface heat. I mean, the needle is long past the area it would even put a remote amount of heat on, which is insanely negligible, before it ever started on that groove again.
Funny how everyone says "According to studies" but never EVER cites the actual study. Take the "stressed vinyl" theory with a grain of salt until someone digs up an actual controlled study.
My first turntable is in this video! The ATPL50. I gave it to my grandma while I upgraded over the years, sadly she passed and now that Audio Technica ATPL50 is very sentimental
Holy crap. You weren't kidding about the quietness of that vinyl - specifically the specimen that was used on the Audio-Technica (21:19). Dead silent! Also interesting to hear the left channel dropout in the master (or production master) tape near the beginning of that song (21:24). Maybe the result of poor handling during splicing or cueing, etc. Makes me think it may have been recorded at 7.5 IPS? Haha, I don't really know. It's uncommon to hear tape dropouts on pressed records though, in my experience. Side note: you have quickly become one of my favorite channels on subjects like this. I wholeheartedly agree with your opinions/testing/conclusions, etc. and I love the lack of audiophile snobbery BS. 🥰
I've genuinely wondered this for as long as i have owned records. And i could not find anyone that has made a good comparison like this. Thank you! You keep putting out great videos.
Wow, thanks, VW! What an effort. Great video. My purchased in 1983 Def Leppard Pyromania album was played about 500 times. Yes, it's beat up, but still is OK.
Wow, this is a fantastic video! The amount of time invested in creating the content, and the level of detail is mesmerizing! Thank you for sharing this with us, it is definitely clear that dust and worn-out styli would be the most detrimental factors for record-groove wear. Congratulations on this great production, keep up the amazing work 🥰
Nice job. There are lots of factors that play into (no pun intended) how much wear a record will show after multiple plays. Keeping them clean and your equipment in good repair are the most impactful. Can't wait for the test regarding colored & new vinyl.
I think it's funny that the dudes who swear a Crosley will literally eat a vinyl record are the same ones who will advise playing without a dust cover for some modicum of improved fidelity. Audiophiles are a superstitious bunch
As with any kind of enthusiasm, being an audiophile has an element of subjective emotional response or nostalgia. In the face of that, taking an objective, critical approach to music appreciation, analysis or creation can be challenging. When people feel like their beliefs are being challenged the knives can come out.
Technics SL-1900 - "my good turntable" ... Thank you VWestlife for getting me into listening to records again, your SL-1900 review/repair video did it actually, grabbed a "not working" one right away... :)
Thank You for the SKILL and TIME you invested into this series of experiments. Talk is cheap but definitive experimentation with published results is conclusive. EXCELLENT SCIENTIFIC DEMONSTRATION !!!
Finally a real answer to this question, thank you! I just got into collecting records as a hobby about 2 ish years ago and reading about record care caused me some anxieties. I want to take great care of them so i can listen to them for years to come and people discussing it never seemed to know the truth. I never really knew if i had the right equipment or not due to all the conflicting research. Or even if just playing them too much harmed them. Now this video has helped greatly ease some of these worries, it's not the playing but the method of storage and cleanliness/care of them when not in use. Thank you!
My original copy of the Star Wars soundtrack is basically unplayable 45 years later because I abused it, Never cleaned it and played it almost daily for many months in a row. My childhood friend still has his original copy and it sounds fine even though he played his just as much, possibly more. The difference is, I was a slob and never cleaned mine and he was meticulous in handling and removing dust and dirt from his vinyl. I was Oscar, he was Felix.
You might have a problem with mold. Since you have nothing to loose with that record, I suggest you to try my method, which brought back many unplayable records to G+ or even better condition. If a record is highly contaminated with greasy fingerprints and dust, it gives fuel to mold. If I come across a record with unknown history and it is heavily distorted, first I use a high concentration sodium hypochlorite (bleach) solution used for removing mold from walls (called SAVO in Europe), I soak the grooves on both sides for about two minutes, than rinse it thoroughly with tap water. Be careful to avoid the label with the bleach, as it will fade it! You need a solution made for mold removal, regular bleach (at least what they sell in Europe) is not concentrated enough. Than I wipe the record dry with soft paper towels, and this time I soak the grooves with formic acid based limescale remover for about 5 minutes, than I rinse it with tap water, and as a final step, I rinse off the tap water with ~ 1 liter of deionised water per side, and let it dry on its own for a night, hung up on its center hole. The hypochlorite dissolves mold and most other organic contaminants, the formic acid dissolves limescale that might be present in the grooves from a previous flooding or from wet playbacks. After this, you need to replace the inner sleeve as it is probably contaminated with mold spores.
I used to get very OCD about playing records, putting a little dust-collector brush on the records before lowering the arm, wiping each side with a special anti-static cloth, making sure the inner record sleeve went into the outer with the openings at right-angles. If I was very good, I never even got to hear the music, and the dust bug caused the record to slow so the music was noticable off-key. I got fed up with this rubbish in the end, and wished there were a way of listening without all the faff. And then came cassettes!
Initially I wasn't going to watch through the whole video non-stop, but then I just did. Fantastic work! You're probably the mastermind in making your videos interesting and engaging.
Totally awesome! I've been saying for a number of years now that the audiophiles are spreading urban legends. I very much appreciate your thoughtful, compelling testing of one of these claims. Bravo!
I panicked about the “rest and relax” bit because I’ve been known to listen to a favorite record multiple times in the course of the day, so your results made me wipe my brow and shout “Whew!” 😊 I really appreciate the time and effort you took with this video… it was both informative and fascinating! Thank you!
lol "Fundamendalist Brady Bunch" xDD And i love that you are one of the very few veteran youtubers who still produces quality content without Style-over-substance bus getting to the point to answer some questions in a practical manner that barely anyone else does. Trust me, Kevin. It is MUCH appreciated. I'm still glad i found your channel MAny many many moons ago.
Thank for all the effort making this very interesting video. I have records that I’ve played 100+ times, even with ceramic cartridges, that still sound as new. Keep your records clean and do not use worn needles and the wear is minimal. What I did notice however, was that American pressings from the seventies show even less wear than the cheap French ones I bought back then.
Excellent informative video. As a record collector, jukebox collector and restorer, I would add that yes, keeping the records clean is important, as well as brushing dust off the stylus regularly, which you were not able to do. Jukebox records Were 45 rpm records, which often were recorded very loud, which increased playback wear, and esp. ones from the 1960s and 1970s, were not always properly mastered and cut, as they were "engineered" to play loud on the small cheap portable phonos of the day. Finally, about the dust thing, I have a Seeburg Background Music System that plays special 16 rpm records, designed to play continuously for background music, and the entire cabinet has weatherstrip to seal it from dust; they knew how damaging dust can be to records.
This analysis & test protocol was insane. So much great thoughts went into designing the test and the video editing is amazing. Really this hould be seen by everyone.
I have this same record, and i am amazed, and impressed that you listened as many times as you have. No idea how many times my copy has been played, I inherited it from my grandma, but ive listened to it once in 10 years
Kudos to you for both this badly-needed test and for the astonishing patience you exhibited by subjecting yourself to the Marcus Family so no one else would have to.
You have the patience of a saint 😂. Also I think it should be noticed that nearly all the "studies" come from people with interests in them, of course the record companies will be very happy if you bought the same record time and again because "it has worn out", and the "audiophiles" have to claim they hear things others don't, etc, etc.
Thank you SO much for your big efforts in making this video and conducting the test. It is extremely interesting (and also reassuring as a vinyl enthusiast).
Thanks for doing this test. It explains why records I used to play on a Fisher Price record player back in the 80s still sounded pretty decent. I was taught to handle records carefully as a child and I guess it paid off!
Excellent, fascinating video. Being a fan of vinyl recordings for many decades I've always wondered about progressive degradation through repeated playback. You've approached the subject very scientifically, addressing all the relevant variables, methodical and keeping in mind possible bias through perception and subjective listening. I've spent a lifetime comparing high end audio equipment, even watching UA-cam is fed through a high end hifi amplifier and quality full sized stereo speakers. The unplayed recording sounded almost holographic and is clearly a well produced disc, I'd describe it as though air passes between the voices and the instruments, the high treble sounding clear and unbound from the instruments unlike modern compressed mp3 recordings which feel like the voices are bogged down somewhat. Going on to the played 50 times, I could definitely hear some loss in the upper treble, perhaps because I'm listening through my hifi or perhaps due to my auditory physiology. Back in the '80's I read a research article which stated that Japanese hifi was tuned differently for the Japanese domestic market than it was for items exported to the west as the hearing range was different either through conditioning because the musical instruments played in the east had far more upper treble or because the auditory physiology was different. After reading reviews in hifi magazines I would venture out to a store and listen for myself. Time and again I would find that what was described as neutral or dry, was often dull and muffled and what had been described as bright or coloured was actually more alive and involving. I now find that time has caught up with my original assessments and hifi equipment now has a much broader and open range than back in the '80's but model digital recordings whilst ultra clear are often soul less in a way that vinyl never was. Of course one variable we can't control for, is the ageing process and the eroding of our ability to register the upper frequencies. From personal endless testing with styli, I've found that the lightest weight produces the most detail from the recordings, whilst it may not produce the strongest slam in the bass it gives me some comfort that it's exerting less wear on the grooves of the vinyl. Thank you for your time and effort in the production of this video.
I often wonder about service guides from the 50's and 60's. If their facts are correct. I have many of these guides. You've proven that, at least one, guide was correct (RCA). This has me wanting to read more specs in the old user/service guides. Well done!
Really appreciate the effort you put into this! Answering some questions I've always had and alleviating some worries I've always put in effort to assuage while still actually enjoying my records.
I was only listening to the video while working and I was thinking to myself "Wow, he's spending a long time on this first recording", before looking over and realizing you had actually just spliced them together perfectly. Impressive editing! As for the music, it actually wasn't half bad, despite it giving me "Toe-tapping Country Gospel Music Hour" PTSD flashbacks. Probably unlikely to end up on any of my playlists, though
Thank you so much, for your detailed and extensive effort in doing this. I was a vinyl DJ for decades, and through experience knew that most of the 'bro science' surrounding vinyl was completely exaggerated. While audiophiles spent £5000+ on special record cleaning machines, I would hand wash mine in a sink where I cleaned the dishes, and you know what, my vinyl sounded fantastic.
A "friend" borrowed my near-new copy of the first Montrose album (one of the best packages of enjoyment per gram out there, even today) and returned it caked with pizza fingerprints. After suitably cursing him out, I washed it extremely carefully in the sink with dish detergent. It really still sounds quite decent today! That said, after using Discwasher for decades, I am seriously considering a record cleaning machine. My remaining time is worth it.
I love your videos so much because they make me feel so much better about using my old equipment without the worry that I'll be destroying it. Seriously, all of your testing and debunking videos are massively appreciated! Btw that humor is on point 👌
"Facts are meaningless - you can use facts to prove anything that's even remotely true! Facts schmacks..." Thanks, Kevin - I really enjoyed the video and I appreciate both the effort you put into it and the consideration you took regarding both approach and presentation. And I wish you a minimum of negative comments from those who refuse to have their beliefs/positions challenged by pesky things like evidence.
Thanks for all the effort in making this one. Just in case no one else said it. If people are still worried about wearing out their disks, they could always do what people did back in the day. As soon as you get your new album back home and play it for the first time, make a copy of it. Be it cassette, cd, or digital. Then you can play it as much as you want and not worry about wearing out the vinyl. And you can carry it around with you.
I had a friend who would do that back in 1978. He had a decent rig at the time, and while the cassette tapes sounded good, I thought that he was being a bit too fussy about preserving his records. I always preferred the vinyl over the sound of the tapes.
Excellent video! Everytime I raised my finger to ask a question or to ponder a what if moment - it was immediately answered! Turns out analog carriers are quite resilient, on the other hand digital gave us the ultimate solution - in essence todays tech solved audio recording and reproduction - there is nothing to improve - ADC/DAC/AMPs are almost flawless, anything what is left to improve is the room and the speakers.
Thank you very much for conducting the tests. I think that individuals who follow and subscribe to your channel, can be rest assured about playing vinyl now. I can now play my stored and treasured vinyls, with the assurance that they will last a lifetime, at the amount of times I do play vinyls during a given year... Once in a while. 😊👍👌💯
Loved this video and all your others. Been watching for a long time and from one old timer who believes in the KISS principle no one does this stuff better than you. Thanks for all your work.
Great video. I think we live in a golden age for cartridges - for just $170 you can get one with a micro linear stylus, the peak of vinyl playback technology. Distortion-free opera and classical vinyl, which is about a challenging as it gets. Even elliptical styli struggle. Audio Technica At-Vm95ml FTW
Just wanted to say THANK YOU for this video - it's really appreciated the time you took, the effort you made and explanations you provided. I have a light tracking turntable (1.2 grams) and can rest assured that with regular washing/maintenance for both the turntable and the records, I can be confident that my records will last several lifetimes
love this channel, might get into vinyl one day because of it. Still have a lot to learn about this sort of stuff, and your “no BS” approach to the facts soothes the mind.
Another top notch video. I've said for years, that the reason most were ever soured on vinyl was they were careless and lazy with it and that most of their disappointment in vinyl playback was self inflicted. I agree with everything you've demonstrated in this video. It's why I prefer compact disc; I'm lazy. I'm not careless, but I am lazy.
Excellent, well-done scientific, controlled study! I still have my records from the 70s. I always bought decent quality equipment to play them on, upgrading through the years. And, I kept them clean using a Discwasher, and cleaned the stylus after every play with a Discwasher brush. They still sound perfect today, and you proved why. I also remember reading about letting records 'rest' between playings, and you proved that there is some truth to this. I really liked that you thought to check them with a 'lower quality' cartridge and stylus, as you are probably correct in thinking that the Stanton tracks lower in the groove (or contacts more surface area) and therefore will sound better on the 'worn' grooves. Well done.
Hey Westlife i’ve been watching since about 2017 but went thought all your old uploads and just wanna say your great! Glad to see your still active after all these years!
Hat off to do this test, wow. What I did after buying a record, is recording it directly on tape, mostly directly at the first play because the record was free of dust and the surface noise was less/low. When I wanted to hear the record, I played the tape. After this, I put a purchase note (price and date) inside the slipcover and put the record back into it's inner sleeve (with the opening on top) into the slipcover. To protect the cover (and the record), I used transparent plastic sleeves. This brings up a next question, there where some rumours around that using plastic sleeves is bad for the records because of acids used in the transparent plastic. After all those years, the records seems to be fine, looking like brand new. So what is true about plastic sleeves? The only thing I noticed is that some of them starts to get brittle over time. Nice subject and video, thanks for making and sharing.
You always do good test. Back when I was way younger I never changed out the cartridge that often, and had one of those drop down suitcase-type stereos. My records still sound pretty good, though I've upgraded my system many times over time.
As someone who got sick from the Audiophile hobby after doing some research about turntables, I just wanted to say your videos further reinforce my sceptics and my thoughts on how the entire industry in full of Placebo Effect. Keep up the amazing work.
I think what does records in quicker than anything is rough/improper handling and playing them on defective equipment (defective stylus, defective cartridge, improper tracking force, mechanical defects with the turntable, etc.). On that note, I've seen new styli and cartridges that had some sort of defect that caused immediate record damage, and that's why I use junk records for testing when I repair a record player or turntable.
I admire your passion ( not surprising after watching so many of your videos) your grit and dedication and above all your generosity in sharing your findings. As a chemist who’s one of the responsibility during the professional career was experimental designs I am also admirative of your testing methodology, your self questioning and hypotheses posing Thank you kindly
Cool video, thank you! Many, many years ago, probably 55+, in a classroom open house evening, the teacher had me bring my Sears portable stereo and it played Walt Disney's "It's A Small World" soundtrack LP over and over for maybe 2 hours. The side maybe ran 10-15 minutes. I still have it and have played it many times over the years since I got it new in 1964. Today, it sounds excellent when I play it on any of my turntables, Technics, Accutrac, AT-LP120(original version) and AT-1240. I use various different cartridges like the Shure M97xe and various AT's(including ML stylus). My Sears portable stereo, which I got new for Christmas 1965 and the school exhibition was Spring 1967. The record changer was made by Warwick? which Sears took over. The stylus was original and probably a conical Sapphire. Now, records were made of different materials, vinyl being the best. If you repeatedly played a 45 rpm single made of poly-styrene, the record wouldn't last very long. I did that too, once. Styrene records used in commercial broadcast radio stations, played on the usual professional turntables(QRK, Russco, Sparta & Gates), wore out rapidly and had to be replaced often. Stanton or Shure cartridges with conical diamond styli were the usual choices. The records would first experience cue-burn at the beginning of the record from back-cuing(especially when stylus replacement was neglected) and then wear would be evident throughout the rest of the record. The styrene records were often favored in jukeboxes. They didn't warp and could withstand atleast 100 plays. Jukes normally used diamond or sapphire conical styli and typically ran at 3-5 grams for the later jukes. Jukes were on location to make money so the operators checked and replaced styli routinely. The more plays you could get out of a record the more money they made.
Excellent test. I did hear a small difference in what I think was the Quasar recording, in that there was a very slight reduction in high frequency noise particularly in the right channel, and a slight increase in surface noise. I couldn't hear a difference that I would attribute to the Audio-Technica or Technics. I have done similar tests myself, albeit without a control (as you correctly pointed out at the time) using a cheap GPO-branded turntable. That did cause obvious damage to the record after 50 plays, including significant distortion, damage to the right channel due to the lack of anti-skate, and high surface noise. Some time ago I did a test over at Audio Appraisal where I played a record 50 times on an AT-LP60, almost non stop without allowing a settling period between plays. At the end of that test there was no damage what-so-ever to the record. With all that said I have spent years studying everything I can find concerning vinyl reproduction and turntable design and engineering, as I build turntables. I've come to the conclusion that it isn't tracking force, stylus shape or stylus material taht influences record wear, but the quality of the mechanics at play. For example if your tonearm has wobbly bearings, the stylus can't track the groove properly so will cause more damage. Likewise if the platter is eccentric or undulates as it spins, the result will be more damage. I do believe that the cheapest turntables (the suitcase style things) cause an unacceptable level of damage in a short period of time. But I do also believe that a turntable that gets the basic mechanical elements right, like the LP60, shouldn't cause any damage. For what it's worth the Technics SL-QD33 is one of the best P-mount cartridge turntables they made. The tonearm uses the same 0.7MG low friction gimbal as an SL-1200, it has non-contact end of play sensing, and the coreless direct-drive motor is immune to cogging. It might look like an ordinary albeit half decent autoamtic 80s turntable, but it's actually one of the best of them ever built. Find an original Technics P30 cartridge for it though.
I think that 1979-era Quasar turntable with the ceramic cartridge (part of an all-in-one combo stereo) was better designed and manufactured than many low-end turntables made today. I used to have a Technics SL-QD33 and actually miss it, I underestimated its quality but among things it had the lowest noise floor of any turntable I'd ever owned.
@@peacearchwa5103 No doubt it was better built. Even the lowest end BSR of the time didn't generally have much play in the tonearm. The low end turntables of today mostly have a couple of plastic pins as tonearm pivots. I would very much like to see @vwestlife repeat the test with the same record on a Crosley Cruiser or similar now that the control samples have been obtained.
Thanks for a very thorough testing video. I appreciate the time you put into the testing and video. The good quality of the pressing helps. I purchased Elton Johns Blue Moves double album when it first came out. The pressing quality was dreadful lots of noise, crackles etc.. I sent it back to the label. They sent me a replacement - equally dreadful pressing quality. Dave.
What an absolute beauty of a video! I'm not a vinyl nerd or an audiophile, so I wasn't sure how interesting I would find this video, but, boy, did I! Not only did you spend an inordinate amount of time to simulate real world conditions, but your methodology is implacable. It's such a joy to see rigorous methodology and good, thorough, and relevant testing. Well done! This may all have been my imagination, but from the two passes of the Q record I thought I could hear a very slight decrease in richness of the sound after 50 and then 100 plays. Maybe it was some transient artifact of the UA-cam compression, or maybe it was all psychological, but the side by side comparisons did sound ever so slightly different in richness to me. However, I couldn't say what exactly it was and if I didn't have the comparison a few seconds earlier and really strained to see if I could hear any difference, I wouldn't. It might well all be in my head, but I didn't expect to hear any difference at all, which is why I was surprised. I am very unsure.
Lots of people talk and worry about vinyl records wearing out, but finally here is a controlled, long-term experiment to test how much audible wear actually happens to records played in real-world conditions on a variety of turntables. I highly suggest a quiet listening environment and good pair of speakers or headphones to observe the results.
However, the main takeaway from this test is something that experts have already known for the past 75 years: dust, dirt, scratches, fingerprints, improper storage, and a worn stylus are the real enemies of vinyl record life, not the kind of turntable you use. Do your best to avoid those perils, and your records will provide a lifetime of enjoyment, even when played on inexpensive equipment.
FYI: The records I tested are slightly transparent when held up to a bright light, indicating they were made with a vinyl formulation which used dye instead of carbon black; these records (marketed under various names such as "Super Vinyl", "Quiex", "UHQR", etc.) are known for their very low surface noise and anti-static properties, but sources differ on whether they last longer or actually wear out more quickly than conventional vinyl.

(Yes, the unplayed record actually has more pops & clicks than the ones that were played 50 times. Maybe it has some dirt in the grooves, and/or was a noisier pressing than the others. None of the LPs came with inner sleeves -- they just put the record directly in the cardboard jacket.)

p.s. I found the obituary for the father of the group, which says the Marcus Family Singers were formed in 1974 and were active for seven years, and recorded two albums: www.petersonbrothers.com/obituaries/calvin-marcus
Also I looked up the songs on the album in the copyright database and several of them were written in 1980, so the album is probably from 1980 or 1981.

@VWestLife Thank you for going into this level of details for our benefit and enjoyment 😊
Beautifully executed tests, thanks Kevin, I won’t look at my SC-12H with a suspicious eye ever again 😸
When I was a child, I had an LP of "Help" by The Beatles that played it so many times that it ended actually worn out.
The record player was a suitcase Denky turntable.

it didn't get any better.

06:40 - Say what you will about RCA, the fact that they implied (with a straight face no less!) that an audiophile will "show off his sound system to friends" more times than actually listening to the records themselves is both extremely hilarious and fairly spot-on.
Yes, audiiophiles listen to their equipment, while the rest listen to the music.
You know about that audiophile stereotype... "Audiophiles use music to listen to their gear."
I feel one of the reasons for this is that audiophiles play those songs so often for friends that they tire of them and do not want to listen to them when alone. I guess it's too much of a good thing.

I bet more people listened to the Marcus family in the last day than have ever before.

Honestly it’s a minor miracle in and of itself that these records are playable at all. If they were handed down at a church (which is implied by their quantity) they would be either played to oblivion by fundies or tossed into the most forgotten corner of the house. Maybe the distributor themselves gave them/sold them to the thrift store?

@@azjames8789 Techmoan has debunked audiophile nonsense. For example there was the video where some company sold a device to shave the edges off compact discs. They claimed this increased fidelity. On a CD.
back in the sixties i left a party and returned in the morning to find my brand new Roling Stones album had been left on repeat overnight for several hours, the record showed no signs of wear at all and fifty years later after countless plays it still sounds fantastic on modern equipment.
same hear he says 50 plays, no way we all played our AC/DC records every weekend for 40 years and they still sound great more like 50 plays a year
I agree, we all buy used records and play them on our high end stereo systems and they sound great. You can imagine those same albums were played on all kinds of cheap systems in the past. Stop worrying about the records and enjoy the music you love.
A good player with a new stylus will leave no audible deterioration with less than 50 plays :)
Facts that happen to me too and my record is like 50 years old still sound good just got to keep them clean n dust free 😂
If it was a pressing of "Hot Rocks" I could never find one that didn't have flaws. They came from the factory with flaws, and it always sounded like massive record groove wear.
These aren't mere clickbait fripperies, these are informational videos for the ages. Basically you can play your records as often as you want.

How so? I think "vinyl snobs" are all well aware that with a good table and good cart you can play your vinyl records without fear of harming them. Matter of fact, most of them preach this when folks tend to worry about it.
@@wymotome Vinyl snobs are those folks that came up with utter bs like Vinyl rest, for 24 HOURS. Silly Or that it is time to replace your vinyl after any number of plays.
You are correct that those that say, keep your gear clean are spot on.
This well thought out and logically performed test put to rest that snake oil statements made by folks generally selling pollihollow thermofuzz fake remedies, are shown to be disingenuous.
Did he ? This guy has his own bias, which is is that he thinks cheap plastic, junk, chinese made crap is okay to play precious record collection on. His whole channel is him being thrifty... or perhaps a hoarder, and playing old beat up crap I would NEVER touch. You guys wanna use crossleys and cheap ceramic carts to play your stuf back fine, but don't start this proselytizing crap. I literally laughed out loud when. he represented some obviously worn, aged, second hand stuff as "high end gear". No. Even his technics is still some belt driven thing with microphonics in the case. he didn't even use modern, new records, trotting out some corny religious stuff. Guy probably listens to the smothers brothers. I imagine his fan base is a bunch of old middle aged men that weren't successful in life and can't afford anything good and so get away with grabbing this kinda junk from the salvation army and trying to represent it as good gear.

I appreciate the fact that you have seemingly gone out of your way to be reasonable with this test.

Kudos to your dedication to getting trustworthy results.
The man employs scientific method in his tests, that’s why he is reliable.
Chrysler came out with an under dash record player for your car that played 45 RPM records. I'll bet it didn't take very long to get some record groove wear on those! And then remember those little cars and trucks that would drive around and round on your record and play it while it drove?
This is exactly what the vinyl community needs right now! People are being shamed to buy expensive equipment right from the get go, and treating vinyl like an extremely delicate form of music consumption, when the thing that greatly impacts your listening experience is dust! Congratulations on this lovely video, keep up with the great work man!
Yes, I was gifted one of those little suitcase players by my daughter. A friend immediately commented on my photo telling me to dump it and sped 300 on a 'good' player as I'll really damage my records. I ignored him and 6 years later im still using it with no issues or damage.vinyl snobs suck.
My family's had many records since the 60s, a lot of them have been played countless times and they are more than 50 years old, but they've always been taken good care of and they've always been played with high quality cartridges with good condition stylus, and many of them still sound awesome.

@@lestatdark2621 Thank you!
Does no one remember that 45s in jukeboxes played all summer long continuously every day without fail?
Ehhhh... I *distinctly* remember hearing severe groove wear out of jukeboxes from time to time. Obviously dependent on a number of factors, but I'm willing to bet that the tracking forces on most of those machines was brutal. I loved watching the fancy automatic changing and playback mechanisms when they had windows, but they always looked like the tonearm was being absolutely slammed onto the record.
Yeah, totally _LoFi_ ...
@@koozmusic Early ones playing mono records maybe, but the ROWE -AMI juke boxes played at very low pressures, as did NSM's and late Rock-ola's. I still have singles played on my ROWE-AMI that used an ortofon om10, and they're perfect. Rock-ola fitted the ACCU-TRAC tonearm to boxes in the 70's onward which was specifically designed for the geometry of a 7 inch record to minimise record wear.
@@analoglooney Hmm, interesting! The OM10 would definitely fall into the hi-fi category, for sure. Perhaps it was just the industrial-looking tonearm and deliberate, mechanical movement of it all that made me think they were rough on records. Then again, these are memories from the 80's and early 90s and I was a child. My dad had a very nice turntable though and taught me how to properly treat his equipment and records at only like 5-6 years old. While I found them infinitely cool, jukeboxes always appeared to handle them in a barbaric way to me. 😬
@@koozmusic LOL, yes they did look very crude and I didn't care much for the SEEBURG and early Wurlitzers. If you're ever out buying 45's you can always tell if they have been played on a Rock-ola. As the records revolve in the carousel they are kept from falling out by a metal band that passes underneath them. This eventually wears a slot in the edge of the records, especially the ones that aren't played a lot. The vendors didn't care as by the time it happened, no-one was playing the record anymore as they were bored with it! The computer controlled ROWE-AMI-s of the 80's also had jewelled arm bearings. Amazing for a juke.
Two VWestlife videos in one week? Awesome! Your videos have been superb since the channel first began.
You give such an objective take. I feel like trying to enter into the hobby is so hard because of the amount of purity test and audiophiles making this seem like you need a budget of at least 2000 to even start. You give real advice that doesn't sugar coat, but also doesn't demonize
Those folks fail to understand that telling people, "You're too broke to engage in this hobby" will never, ever get a person into vinyl listening. Get someone encouraged and started on simple equipment, tell them how to use the cheaper equipment to their advantage, and watch them work their way up! All this special noise equipment is hard to understand, and you have to take it in small portions.
I like that you call out people who waste time on forums, pontificating and arguing about how you should listen to music. They spend more time doing that instead of enjoying their music collection.
But you need those $1000 cables and "hyper shielded power cords" with the 500 lbs concrete turntables to REALLY get clean sound...........NOT!
Music lovers use equipment to listen to their music, audiophools use music to listen to their equipment.
That proves what I've always thought...
It's not what you play them on, it's how you treat them.
Would still feel better about playing an expensive record on a good quality table with a good cart vs. a cheapo Crosley. Even that Quasar is superior to a Crosley.
@@wymotome I agree, but if all you've got is a Crosley, then you don't have to worry too much.
@@frankowalker4662 A Crosley was not tested and I have seen with my own eyes the "Crosley Crop Circles" that those turntables leave behind on newer vinyl. I would not make assumptions based on this video when it comes to Victrola and Crosley as they are different animals than that Quasar.
And for the record, a lot of older vinyl was superior to the newer stuff. I'd like to see the test redone with a few modern "clearance" albums from the local Target.
@@wymotome Good point. I've got one of the UK versions of Crosley. (same design, different brand). But I only ever play my 1960's-1980's, (already scratched), records on it.

That's the problem buying second-hand records. you just don't know how they are going to sound even If they look mint they could be full of dirt and dust and permanently damaged by a worn stylus it's pot luck .
Just WOW!
Big amount of work and systematic approach to tests!
Huge respect!
Many thanks.
THANK YOU for putting another nail in the coffin of the whole "let the vinyl relax" malarkey! I'm not sure why some people in the industry thought it was appropriate to anthropomorphize vinyl records, but it's borderline crazy IMO, especially without data to back up the claim. Much like you, I've found that simply keeping the vinyl clean, and cleaning when necessary, to be the most surefire way to have a great listening experience.
Maybe they were hoping they could talk people into buying more than one copy of albums and singles they liked.
There absolutely are polymer use-cases where you want to give the material time to recover. It is particularly the case with items that deform in use, giving them recovery time slows down polymer creep. EVA shoe soles are an example.
I don't for a second think that records are susceptible to this. Hard PVC has very little creep to begin with. To be a little pedantic it's not PVC but according to Brydson's Plastics a blend with... i forgot, and doesn't matter, the mechanical properties are basically identical. To be kept in mind when you replay it, at least a few minutes have passed with material essentially at rest, after it was under impact for one tenthousandth of a second or so, just... different timescales to such a degree, that i don't see how a few more hours would help.
@@SianaGearz Remember the math question about which put more lb/sq in onto the floor, the elephant or the person wearing stiletto heels?
The stylus radius being 0.2-0.3 mil for even a high quality stylus, and the amount of the groove wall vertically being contacted being on the order of 1 mil, the force pushing the stylus side to side is then being applied to an area of, ballpark, .0000006 inches square, or a multiplication factor of around 1.5 million. So 1.5 g = .0033 lb force, over 5000 psi. A handwave value for one reference's current recipe of 2/3PVA, 1/3 PVC mix in records is around 4000 psi tensile strength. (Not sure of exact grades mixed, but PVA is quite a bit softer and somewhat less crystalline than PVC.) Plus the stylus is applying a very significant thermal spike for those milliseconds. The surprise is maybe that the record surface /doesn't/ quickly degrade, though certainly the stylus is great at embedding dust and other particles into the groove walls. This test by VWestlife is reasonably scientific to the end result of "does it sound immediately different? No." and all of the commenters' related experiences with how poorly 45's in jukeboxes last are also a good bound to show that degradation is indeed happening from worst case high intensity repetition. I'd bet that 45's in radio stations, while probably kept clean, had even worse lives for the first week or two after the A-side hit the charts.
FWIW I know from experience that playing a favorite vinyl album every afternoon after high school before the parents got home, on an ancient record player with a lot of tonearm weight, does indeed wipe out the grooves after maybe two hundred plays. I don't recall playing it multiple times in one day very often. But it certainly sounds like crap now, on a far better rig.
@@pault151 Yes you make a strong case that the stylus has a substantial impact on the groove surface and i agree. I don't know if tensile strength is a good metric since OK there would be tangential tensile impact, mostly compressive, but there is wear for sure.
I also made a brainfart, the polymer used in records is a copolymer not a blend and yes polyvinyl acetate is softer. Brydson specifies 15% acetate used for vinyl records.
It's ultimately not necessarily cut and dry, i mean, we all remember worn records, but was the gradual damage caused by the stylus contact, or was it caused by contamination such as surface dust, and how much of either? Dust can be substantially smaller than the stylus contact patch, which is bad, and it won't be as nicely shaped as the stylus. It's worse if you're tracking at 6g than at 1.5g for sure.
The question here is "letting vinyl relax" and that it does nothing, because whether it relaxes for 3 minutes as you replay the same song over and over, or for 3 days, that's effectively both a very long time compared to the millisecond fractions the groove spends in contact with the stylus. So repeating the record constantly should induce the same wear as playing it for the same amount of time in total but letting it "rest" in between.
I imagine the Marcus Family would be proud that their unused recordings helped in this test, especially since we were all straining, listening so closely to the words and music (albeit for signs of damage 😁)
Fantastic work!
LOL but they would be very unhappy it was in the name of science
This is by far the most thorough and definitive test of record wear I’ve ever seen! Myth, BUSTED.
That vinyl relaxing period theory sounds absurd
I'm not sure. There is a lot of vibration and friction, and vinyl is a relatively soft material. Once every 24h-s is stupid, but playing a record over and over and over and over again, probably creates quite a lot of surface heat.
I studied materias technology at university. Yes it is absurd. It would be a problem only if it were played so fast that it could got the chance to heat up, but It won't heat up not even a little bit and even if it does, it would dissipate it immediately.
@@AnalogSins That would only be possible had the needle continuously ran the same exact groove for hours at a time. Literally impossible. Physics alone disproves this asinine theory of surface heat. I mean, the needle is long past the area it would even put a remote amount of heat on, which is insanely negligible, before it ever started on that groove again.
Funny how everyone says "According to studies" but never EVER cites the actual study. Take the "stressed vinyl" theory with a grain of salt until someone digs up an actual controlled study.
Its like that crap about CDs being repeatedly played !
My first turntable is in this video! The ATPL50. I gave it to my grandma while I upgraded over the years, sadly she passed and now that Audio Technica ATPL50 is very sentimental
Holy crap. You weren't kidding about the quietness of that vinyl - specifically the specimen that was used on the Audio-Technica (21:19). Dead silent! Also interesting to hear the left channel dropout in the master (or production master) tape near the beginning of that song (21:24). Maybe the result of poor handling during splicing or cueing, etc. Makes me think it may have been recorded at 7.5 IPS? Haha, I don't really know. It's uncommon to hear tape dropouts on pressed records though, in my experience.
Side note: you have quickly become one of my favorite channels on subjects like this. I wholeheartedly agree with your opinions/testing/conclusions, etc. and I love the lack of audiophile snobbery BS. 🥰

Wow, this is a fantastic video! The amount of time invested in creating the content, and the level of detail is mesmerizing! Thank you for sharing this with us, it is definitely clear that dust and worn-out styli would be the most detrimental factors for record-groove wear. Congratulations on this great production, keep up the amazing work 🥰
Nice job. There are lots of factors that play into (no pun intended) how much wear a record will show after multiple plays. Keeping them clean and your equipment in good repair are the most impactful. Can't wait for the test regarding colored & new vinyl.
I think it's funny that the dudes who swear a Crosley will literally eat a vinyl record are the same ones who will advise playing without a dust cover for some modicum of improved fidelity.
Audiophiles are a superstitious bunch
As with any kind of enthusiasm, being an audiophile has an element of subjective emotional response or nostalgia. In the face of that, taking an objective, critical approach to music appreciation, analysis or creation can be challenging.
When people feel like their beliefs are being challenged the knives can come out.
A lot of patience and hard work were put into the creation of this video. Thank you very much!
Technics SL-1900 - "my good turntable" ... Thank you VWestlife for getting me into listening to records again, your SL-1900 review/repair video did it actually, grabbed a "not working" one right away... :)
Thank you for all that work. Truly appreciated, as was the cameo by Vaughn Monroe!
Ran across this video by accident...stayed for the whole thing!!! Very informative and The Marcus Family are awesome 😅
It’s beautiful how much effort went into designing the methodology and thoroughly described in details in the video
I applaud your careful scientific approach to seeking the answers. I am relieved that I can play my collection as much as I wish.
Thank You for the SKILL and TIME you invested into this series of experiments. Talk is cheap but definitive experimentation with published results is conclusive. EXCELLENT SCIENTIFIC DEMONSTRATION !!!
Finally a real answer to this question, thank you!
I just got into collecting records as a hobby about 2 ish years ago and reading about record care caused me some anxieties. I want to take great care of them so i can listen to them for years to come and people discussing it never seemed to know the truth. I never really knew if i had the right equipment or not due to all the conflicting research. Or even if just playing them too much harmed them.
Now this video has helped greatly ease some of these worries, it's not the playing but the method of storage and cleanliness/care of them when not in use.
Thank you!
My original copy of the Star Wars soundtrack is basically unplayable 45 years later because I abused it, Never cleaned it and played it almost daily for many months in a row. My childhood friend still has his original copy and it sounds fine even though he played his just as much, possibly more. The difference is, I was a slob and never cleaned mine and he was meticulous in handling and removing dust and dirt from his vinyl. I was Oscar, he was Felix.
I had a collection from my childhood that went through a lot. I was able to bring most of them back using cleaning vinegar and warm water
You might have a problem with mold. Since you have nothing to loose with that record, I suggest you to try my method, which brought back many unplayable records to G+ or even better condition. If a record is highly contaminated with greasy fingerprints and dust, it gives fuel to mold. If I come across a record with unknown history and it is heavily distorted, first I use a high concentration sodium hypochlorite (bleach) solution used for removing mold from walls (called SAVO in Europe), I soak the grooves on both sides for about two minutes, than rinse it thoroughly with tap water. Be careful to avoid the label with the bleach, as it will fade it! You need a solution made for mold removal, regular bleach (at least what they sell in Europe) is not concentrated enough. Than I wipe the record dry with soft paper towels, and this time I soak the grooves with formic acid based limescale remover for about 5 minutes, than I rinse it with tap water, and as a final step, I rinse off the tap water with ~ 1 liter of deionised water per side, and let it dry on its own for a night, hung up on its center hole.
The hypochlorite dissolves mold and most other organic contaminants, the formic acid dissolves limescale that might be present in the grooves from a previous flooding or from wet playbacks. After this, you need to replace the inner sleeve as it is probably contaminated with mold spores.
I used to get very OCD about playing records, putting a little dust-collector brush on the records before lowering the arm, wiping each side with a special anti-static cloth, making sure the inner record sleeve went into the outer with the openings at right-angles. If I was very good, I never even got to hear the music, and the dust bug caused the record to slow so the music was noticable off-key. I got fed up with this rubbish in the end, and wished there were a way of listening without all the faff. And then came cassettes!
@@suntexi There were also headshell mount brushes
Initially I wasn't going to watch through the whole video non-stop, but then I just did. Fantastic work! You're probably the mastermind in making your videos interesting and engaging.
Totally awesome! I've been saying for a number of years now that the audiophiles are spreading urban legends. I very much appreciate your thoughtful, compelling testing of one of these claims. Bravo!
I panicked about the “rest and relax” bit because I’ve been known to listen to a favorite record multiple times in the course of the day, so your results made me wipe my brow and shout “Whew!” 😊
I really appreciate the time and effort you took with this video… it was both informative and fascinating! Thank you!
lol "Fundamendalist Brady Bunch" xDD And i love that you are one of the very few veteran youtubers who still produces quality content without Style-over-substance bus getting to the point to answer some questions in a practical manner that barely anyone else does. Trust me, Kevin. It is MUCH appreciated. I'm still glad i found your channel MAny many many moons ago.
Thank for all the effort making this very interesting video. I have records that I’ve played 100+ times, even with ceramic cartridges, that still sound as new. Keep your records clean and do not use worn needles and the wear is minimal.
What I did notice however, was that American pressings from the seventies show even less wear than the cheap French ones I bought back then.
New VWestlife video on the Fourth of July! I didn’t know there was presents on 7/4 but I accept!
Excellent informative video. As a record collector, jukebox collector and restorer, I would add that yes, keeping the records clean is important, as well as brushing dust off the stylus regularly, which you were not able to do. Jukebox records Were 45 rpm records, which often were recorded very loud, which increased playback wear, and esp. ones from the 1960s and 1970s, were not always properly mastered and cut, as they were "engineered" to play loud on the small cheap portable phonos of the day. Finally, about the dust thing, I have a Seeburg Background Music System that plays special 16 rpm records, designed to play continuously for background music, and the entire cabinet has weatherstrip to seal it from dust; they knew how damaging dust can be to records.
The power of JEsus must be like STRONG in your house right now ... hahaha
This analysis & test protocol was insane. So much great thoughts went into designing the test and the video editing is amazing. Really this hould be seen by everyone.
Any video from you is worth my time to watch it! You simply rock, man!
I have this same record, and i am amazed, and impressed that you listened as many times as you have. No idea how many times my copy has been played, I inherited it from my grandma, but ive listened to it once in 10 years
Compliments from Belgium for your profound testing! Really enjoyed!
Kudos to you for both this badly-needed test and for the astonishing patience you exhibited by subjecting yourself to the Marcus Family so no one else would have to.
Commenting to boost the chance that it shows up on “that guy’s” feed. You know… the one that needs to see it
Thanks for putting in the months to make this video. Loved it. My Soul is now restored.
You have the patience of a saint 😂. Also I think it should be noticed that nearly all the "studies" come from people with interests in them, of course the record companies will be very happy if you bought the same record time and again because "it has worn out", and the "audiophiles" have to claim they hear things others don't, etc, etc.
Thank you SO much for your big efforts in making this video and conducting the test. It is extremely interesting (and also reassuring as a vinyl enthusiast).
Thanks for doing this test. It explains why records I used to play on a Fisher Price record player back in the 80s still sounded pretty decent. I was taught to handle records carefully as a child and I guess it paid off!
Excellent, fascinating video. Being a fan of vinyl recordings for many decades I've always wondered about progressive degradation through repeated playback. You've approached the subject very scientifically, addressing all the relevant variables, methodical and keeping in mind possible bias through perception and subjective listening. I've spent a lifetime comparing high end audio equipment, even watching UA-cam is fed through a high end hifi amplifier and quality full sized stereo speakers. The unplayed recording sounded almost holographic and is clearly a well produced disc, I'd describe it as though air passes between the voices and the instruments, the high treble sounding clear and unbound from the instruments unlike modern compressed mp3 recordings which feel like the voices are bogged down somewhat. Going on to the played 50 times, I could definitely hear some loss in the upper treble, perhaps because I'm listening through my hifi or perhaps due to my auditory physiology. Back in the '80's I read a research article which stated that Japanese hifi was tuned differently for the Japanese domestic market than it was for items exported to the west as the hearing range was different either through conditioning because the musical instruments played in the east had far more upper treble or because the auditory physiology was different. After reading reviews in hifi magazines I would venture out to a store and listen for myself. Time and again I would find that what was described as neutral or dry, was often dull and muffled and what had been described as bright or coloured was actually more alive and involving. I now find that time has caught up with my original assessments and hifi equipment now has a much broader and open range than back in the '80's but model digital recordings whilst ultra clear are often soul less in a way that vinyl never was. Of course one variable we can't control for, is the ageing process and the eroding of our ability to register the upper frequencies. From personal endless testing with styli, I've found that the lightest weight produces the most detail from the recordings, whilst it may not produce the strongest slam in the bass it gives me some comfort that it's exerting less wear on the grooves of the vinyl. Thank you for your time and effort in the production of this video.
I often wonder about service guides from the 50's and 60's. If their facts are correct. I have many of these guides. You've proven that, at least one, guide was correct (RCA). This has me wanting to read more specs in the old user/service guides. Well done!
Really appreciate the effort you put into this! Answering some questions I've always had and alleviating some worries I've always put in effort to assuage while still actually enjoying my records.
I was only listening to the video while working and I was thinking to myself "Wow, he's spending a long time on this first recording", before looking over and realizing you had actually just spliced them together perfectly. Impressive editing!
As for the music, it actually wasn't half bad, despite it giving me "Toe-tapping Country Gospel Music Hour" PTSD flashbacks. Probably unlikely to end up on any of my playlists, though
Another amazing video. I love these needlessly long and tedious tests that you do. This one might set a new level.
"I'm getting a fundamentalist Brady Bunch vibe from it." Thanks, that gave me a good laugh.
Just saw a Yahoo headline today... It said that all of the Brady Bunch kids were 'hooking up' back in the day.
Much Respect for the amount of time and patience that this test took in order to make this video! Well done!
Thank you so much, for your detailed and extensive effort in doing this.
I was a vinyl DJ for decades, and through experience knew that most of the 'bro science' surrounding vinyl was completely exaggerated.
While audiophiles spent £5000+ on special record cleaning machines, I would hand wash mine in a sink where I cleaned the dishes, and you know what, my vinyl sounded fantastic.
A "friend" borrowed my near-new copy of the first Montrose album (one of the best packages of enjoyment per gram out there, even today) and returned it caked with pizza fingerprints. After suitably cursing him out, I washed it extremely carefully in the sink with dish detergent. It really still sounds quite decent today! That said, after using Discwasher for decades, I am seriously considering a record cleaning machine. My remaining time is worth it.
I love your videos so much because they make me feel so much better about using my old equipment without the worry that I'll be destroying it. Seriously, all of your testing and debunking videos are massively appreciated!
Btw that humor is on point 👌
"Facts are meaningless - you can use facts to prove anything that's even remotely true! Facts schmacks..."
Thanks, Kevin - I really enjoyed the video and I appreciate both the effort you put into it and the consideration you took regarding both approach and presentation. And I wish you a minimum of negative comments from those who refuse to have their beliefs/positions challenged by pesky things like evidence.
This is another great video, I love that Michael Fremer clip, for all his talk he knows very little about how records are made.
Thanks for all the effort in making this one. Just in case no one else said it.
If people are still worried about wearing out their disks, they could always do what people did back in the day. As soon as you get your new album back home and play it for the first time, make a copy of it. Be it cassette, cd, or digital. Then you can play it as much as you want and not worry about wearing out the vinyl. And you can carry it around with you.
I had a friend who would do that back in 1978. He had a decent rig at the time, and while the cassette tapes sounded good, I thought that he was being a bit too fussy about preserving his records. I always preferred the vinyl over the sound of the tapes.
Back in the day, I used to make a cassette copy of a new album. I even made an 8 track copy of one record, believe it or not.
this video needs to be pinned in every Redit, Tick tok, Instagram and Facebook comment section that talks about record players and turntables.
Excellent video! Everytime I raised my finger to ask a question or to ponder a what if moment - it was immediately answered!
Turns out analog carriers are quite resilient, on the other hand digital gave us the ultimate solution - in essence todays tech solved audio recording and reproduction - there is nothing to improve - ADC/DAC/AMPs are almost flawless, anything what is left to improve is the room and the speakers.
Thank you very much for conducting the tests. I think that individuals who follow and subscribe to your channel, can be rest assured about playing vinyl now. I can now play my stored and treasured vinyls, with the assurance that they will last a lifetime, at the amount of times I do play vinyls during a given year... Once in a while. 😊👍👌💯
Loved this video and all your others. Been watching for a long time and from one old timer who believes in the KISS principle no one does this stuff better than you. Thanks for all your work.
Great video. I think we live in a golden age for cartridges - for just $170 you can get one with a micro linear stylus, the peak of vinyl playback technology. Distortion-free opera and classical vinyl, which is about a challenging as it gets. Even elliptical styli struggle.
Audio Technica At-Vm95ml FTW
I have one of these, and I play a lot of classical music. If you can afford it, get one. You will be amazed.
Just wanted to say THANK YOU for this video - it's really appreciated the time you took, the effort you made and explanations you provided. I have a light tracking turntable (1.2 grams) and can rest assured that with regular washing/maintenance for both the turntable and the records, I can be confident that my records will last several lifetimes
And there rounding the last corner! It's neck to neck as they come to the needle!!
love this channel, might get into vinyl one day because of it. Still have a lot to learn about this sort of stuff, and your “no BS” approach to the facts soothes the mind.
Very interesting experiment, thanks for putting all that time and effort in!
Another top notch video. I've said for years, that the reason most were ever soured on vinyl was they were careless and lazy with it and that most of their disappointment in vinyl playback was self inflicted. I agree with everything you've demonstrated in this video. It's why I prefer compact disc; I'm lazy. I'm not careless, but I am lazy.
That virgin vinyl joke made me die
You're awfully good at writing UA-cam comments, for a dead person.
Sounds a bit dirty - like a doll that's still in its box and hasn't been inflated yet!
Excellent, well-done scientific, controlled study!
I still have my records from the 70s. I always bought decent quality equipment to play them on, upgrading through the years. And, I kept them clean using a Discwasher, and cleaned the stylus after every play with a Discwasher brush. They still sound perfect today, and you proved why.
I also remember reading about letting records 'rest' between playings, and you proved that there is some truth to this. I really liked that you thought to check them with a 'lower quality' cartridge and stylus, as you are probably correct in thinking that the Stanton tracks lower in the groove (or contacts more surface area) and therefore will sound better on the 'worn' grooves.
Well done.
The lord works in mysterious ways....even with vinyl.
But only with virgin vinyl! 😁
@@marks-the-spot All right, no more religious jokes 😅
This was a joy to watch! And I was certain we were all in good hands of this being an accurate test. Excellent job as always!
I gotta have that Marcus Family album - it's imprinted in my brain now, fifty times over.
A lot of work. Thanks! That girl has a very nice voice and the recording quality of that record isn't bad at all.
This is some dedication.
You're doing science.
Hey Westlife i’ve been watching since about 2017 but went thought all your old uploads and just wanna say your great! Glad to see your still active after all these years!
Wow, I didn’t know I needed this. The video was actually REALLY worth my time!
Hat off to do this test, wow. What I did after buying a record, is recording it directly on tape, mostly directly at the first play because the record was free of dust and the surface noise was less/low. When I wanted to hear the record, I played the tape. After this, I put a purchase note (price and date) inside the slipcover and put the record back into it's inner sleeve (with the opening on top) into the slipcover. To protect the cover (and the record), I used transparent plastic sleeves. This brings up a next question, there where some rumours around that using plastic sleeves is bad for the records because of acids used in the transparent plastic. After all those years, the records seems to be fine, looking like brand new. So what is true about plastic sleeves? The only thing I noticed is that some of them starts to get brittle over time. Nice subject and video, thanks for making and sharing.
You always do good test. Back when I was way younger I never changed out the cartridge that often, and had one of those drop down suitcase-type stereos. My records still sound pretty good, though I've upgraded my system many times over time.
I have 40 year old records played on the same stylus hundreds of times each. They're next to indestructible, just make sure they're clean.
As someone who got sick from the Audiophile hobby after doing some research about turntables, I just wanted to say your videos further reinforce my sceptics and my thoughts on how the entire industry in full of Placebo Effect. Keep up the amazing work.
I think what does records in quicker than anything is rough/improper handling and playing them on defective equipment (defective stylus, defective cartridge, improper tracking force, mechanical defects with the turntable, etc.). On that note, I've seen new styli and cartridges that had some sort of defect that caused immediate record damage, and that's why I use junk records for testing when I repair a record player or turntable.
Wow, defective new styli and cartridges with immediate record damage?! You should make a video about that. That's insane!
I admire your passion ( not surprising after watching so many of your videos) your grit and dedication and above all your generosity in sharing your findings. As a chemist who’s one of the responsibility during the professional career was experimental designs I am also admirative of your testing methodology, your self questioning and hypotheses posing
Thank you kindly
Thank you for cutting through all the fudd, and crudd that's been floating around in the vinyl world for far far too long. 🙂
Cool video, thank you!
Many, many years ago, probably 55+, in a classroom open house evening, the teacher had me bring my Sears portable stereo and it played Walt Disney's "It's A Small World" soundtrack LP over and over for maybe 2 hours. The side maybe ran 10-15 minutes. I still have it and have played it many times over the years since I got it new in 1964. Today, it sounds excellent when I play it on any of my turntables, Technics, Accutrac, AT-LP120(original version) and AT-1240. I use various different cartridges like the Shure M97xe and various AT's(including ML stylus).
My Sears portable stereo, which I got new for Christmas 1965 and the school exhibition was Spring 1967. The record changer was made by Warwick? which Sears took over. The stylus was original and probably a conical Sapphire.
Now, records were made of different materials, vinyl being the best. If you repeatedly played a 45 rpm single made of poly-styrene, the record wouldn't last very long. I did that too, once. Styrene records used in commercial broadcast radio stations, played on the usual professional turntables(QRK, Russco, Sparta & Gates), wore out rapidly and had to be replaced often. Stanton or Shure cartridges with conical diamond styli were the usual choices. The records would first experience cue-burn at the beginning of the record from back-cuing(especially when stylus replacement was neglected) and then wear would be evident throughout the rest of the record. The styrene records were often favored in jukeboxes. They didn't warp and could withstand atleast 100 plays. Jukes normally used diamond or sapphire conical styli and typically ran at 3-5 grams for the later jukes. Jukes were on location to make money so the operators checked and replaced styli routinely. The more plays you could get out of a record the more money they made.
Excellent test. I did hear a small difference in what I think was the Quasar recording, in that there was a very slight reduction in high frequency noise particularly in the right channel, and a slight increase in surface noise. I couldn't hear a difference that I would attribute to the Audio-Technica or Technics. I have done similar tests myself, albeit without a control (as you correctly pointed out at the time) using a cheap GPO-branded turntable. That did cause obvious damage to the record after 50 plays, including significant distortion, damage to the right channel due to the lack of anti-skate, and high surface noise. Some time ago I did a test over at Audio Appraisal where I played a record 50 times on an AT-LP60, almost non stop without allowing a settling period between plays. At the end of that test there was no damage what-so-ever to the record.
With all that said I have spent years studying everything I can find concerning vinyl reproduction and turntable design and engineering, as I build turntables. I've come to the conclusion that it isn't tracking force, stylus shape or stylus material taht influences record wear, but the quality of the mechanics at play. For example if your tonearm has wobbly bearings, the stylus can't track the groove properly so will cause more damage. Likewise if the platter is eccentric or undulates as it spins, the result will be more damage. I do believe that the cheapest turntables (the suitcase style things) cause an unacceptable level of damage in a short period of time. But I do also believe that a turntable that gets the basic mechanical elements right, like the LP60, shouldn't cause any damage. For what it's worth the Technics SL-QD33 is one of the best P-mount cartridge turntables they made. The tonearm uses the same 0.7MG low friction gimbal as an SL-1200, it has non-contact end of play sensing, and the coreless direct-drive motor is immune to cogging. It might look like an ordinary albeit half decent autoamtic 80s turntable, but it's actually one of the best of them ever built. Find an original Technics P30 cartridge for it though.
I think that 1979-era Quasar turntable with the ceramic cartridge (part of an all-in-one combo stereo) was better designed and manufactured than many low-end turntables made today. I used to have a Technics SL-QD33 and actually miss it, I underestimated its quality but among things it had the lowest noise floor of any turntable I'd ever owned.
@@peacearchwa5103 No doubt it was better built. Even the lowest end BSR of the time didn't generally have much play in the tonearm. The low end turntables of today mostly have a couple of plastic pins as tonearm pivots. I would very much like to see @vwestlife repeat the test with the same record on a Crosley Cruiser or similar now that the control samples have been obtained.
Thanks for a very thorough testing video. I appreciate the time you put into the testing and video. The good quality of the pressing helps. I purchased Elton Johns Blue Moves double album when it first came out. The pressing quality was dreadful lots of noise, crackles etc.. I sent it back to the label. They sent me a replacement - equally dreadful pressing quality.
Dave.
Boy: Mr. Owl, how many times does it take to wear out an LP record?
Mr. Owl: Let's find out. One. Two. Three [violent scratch noise]. Three!
My ex girl friend said once, she uses multistacking. Note ex gf.😂
What an absolute beauty of a video!
I'm not a vinyl nerd or an audiophile, so I wasn't sure how interesting I would find this video, but, boy, did I! Not only did you spend an inordinate amount of time to simulate real world conditions, but your methodology is implacable. It's such a joy to see rigorous methodology and good, thorough, and relevant testing. Well done!
This may all have been my imagination, but from the two passes of the Q record I thought I could hear a very slight decrease in richness of the sound after 50 and then 100 plays. Maybe it was some transient artifact of the UA-cam compression, or maybe it was all psychological, but the side by side comparisons did sound ever so slightly different in richness to me. However, I couldn't say what exactly it was and if I didn't have the comparison a few seconds earlier and really strained to see if I could hear any difference, I wouldn't. It might well all be in my head, but I didn't expect to hear any difference at all, which is why I was surprised. I am very unsure.
