Oh, god, another insanely expensive gadget the world shouldn't need. I use a turntable with a removable spindle and center discs using a thin stick (often a small artist's paint brush). So simple, so cheap, no electronics, and no reaming.
You can do the same compensation much more cheaply by moving your head backwards and forwards 33 times a minute thanks to the doppler effect. I believe that was the origin of headbanging.
This is very interesting. But my comment is definitely off centre. I was playing The Jefferson Airplane track, Today, and I remembered I bought this album after watching your top 100. I believe you played this song. You are a great man and your work in this field is unparalleled. Many thanks
Michael, good afternoon. after installing the plate on the disc, I insert a thin cambrick into the spindle from above.And I think it helps)).Calculating that the geometry of the disk corresponds to.That's the solution.Thanks for the video!
Fascinating tool Michael. Agree that uncentered vinyl doesn't get enough discussion. Pro tip - might be worth investing in a $20 mini video camera/iphone tripod or clip...it was a little hard to discern what was the needle swaying ...and what your hand held camera work!
nakamichi turntable tx-1000 addressed this very issue of off centred records by way of self-centering mechanism that eliminates the wow caused by the spindle hole being punched off center.
Thanks Michael for a very interesting video demonstration of this highly desirable but alas unaffordable device. Most vinyl records pressed today are a little to a lot off centre, usually on one side only. Why the pressing machine manufacturers cannot address this so that it is eliminated is astounding to me, to be honest. I think, from experience, the Canadian WarmTone presses do a much better job at pressing concentric vinyl than any other. A pressing plant here in Ireland, Dublin Vinyl, has a few WarmTone presses and I have never seen such perfectly centred spindle holes ... on both sides! I would say, based on what I have seen, Dublin Vinyl is as good if not better than anything pressed in Japan in terms of concentric vinyl. Warner Pioneer Corporation in Japan were absolutely ace in this aspect of record manufacturing, exceeding JVC easily, based again on my experience. What I did not fully understand though about the DS Audio device is that, yes, it will tell you that the record as positioned on the spindle is 'off centre'. You can, as you did, 'play around' with this and sometimes you will get the record to spin concentrically. If however, the spindle hole needs correction, the DS Audio device does not appear to tell you where the problem lies? You will need to 'shave' a particular part of the spindle hole with a reamer or a round file in this case, but it is vital that you 'shave' or enlarge the correct point where the record edge juts out most, on rotation. Must this be done with your eyes? Despite the exciting technology that this accessory presents, it is up to you, the user, to intervene when a spindle hole needs to be corrected? I have been fixing 'off centre' spindle holes for years to the point now that I can do this extremely well, neatly and 'invisibly'. I like to call it 'invisible mending'. I had to fix one record of a 2LP set that I bought as recently as last Saturday. Record 2 was visibly 'off' and I had to intervene. The record was the recently reissued Paul Weller '22 Dreams' reissue on Island Records, pressed at Record Industry in the Netherlands. It now spins beautifully, concentrically and the spindle hole looks unchanged. I think the improvements we heard in your video when a record is correctly centred, were undeniable. It a shame that this device is so costly. It puts it outside the financial reach of most people. Speaking personally, while I could afford it, I can do the exact same job using my eyes and my round file. I don't play 'off centre' records without first fixing them. It takes practice to become adept at this, but practice does make perfect. I am greatly looking forward to your website which I understand will be up and running next month. Greetings from Cork, Ireland!
@@Fluterra Isn’t that precisely what I said? Read my response again. I have been doing this for years. If you are blessed with decent eyesight and know what is involved you certainly don’t need to drop $6k on this device which simply tells you what should be already obvious. Spin the record on your turntable and note where the outer rim protrudes most on rotation. The spindle hole needs to be adjusted at the point that directly coincides with the point on the outer rim. I hesitate to use the word ‘enlarge’ and prefer ‘shave’. If you ‘enlarge’ the spindle hole excessively you run the risk of ruining the record. It’s easy once you get the hang of it, but it needs practice. Most spindle holes look exactly the same on my records even after adjusting them. Hence my use of the phrase ‘invisible mending’. Oftentimes the off centre rotation is caused by part of the paper label extending beyond or over the spindle hole. A gentle ‘shaving’ back of the paper with a round file will achieve concentric rotation.
The problem of off-center records is, in my view, underappreciated by audiophiles. Archivists use turntables with removable or smaller-diameter spindles, and making sure every record runs true is best archival practice. I noticed the effect more on the piano record, but bear in mind that the effect is stronger the nearer you get to the label.
Absolutely. I bet CD fans found that unforgivable. While doing lots of DIY mods to vintage record players and learning of Nakamichi Dragon-CT I just could not reconcile this awful aspect though my hifi buddy swore it was unimportant as the headshell swung side to side...
Removing the spindle is probably the easiest solution to adjust the record. Since a smaller spindle still limits on any majorly off center pressings, but honestly those will have bad edges of the record with no lead up deadwax. I'd actually feel using a cheap USB microscope that you can easily place above the turntable, then you check the runout groove like they do at stamping plants to check for proper centering and adjust the record, let it spin and draw a dot in the center with a marker to remark the center hole for reaming. Sure the marker isn't pretty, but you're also effectively redrilling a hole to fix a pressing error. So I'd figure the value of the record to actually improve the sound quality would improve value for playability.
On the second record the violin sounded sweeter after correction, more natural. Please Michael,can you do an in depth video on your new OMA K3 please and hopefully at some point a factory tour!
Puts me to mind of the Nakamichi Dragon Computing Turntable from the '80s...which among other things was supposed to be able to detect and correct for off-centre pressings...
Another option would be to fit a slightly smaller spindle on your platter, if your turntable allows. I’ve seen this done for archival/restoration work. That way, you wouldn’t have to file your spindle hole.
I don't know why people don't come up with an accessory that's a piece of transparent plastic disc that's placed over the playing vinyl with multiple accurately printed concentric circles so the user can adjust the record lining up the run-out groove with one of the circles. You don't get the $5K sensor but you can eyeball it to pretty close accuracy. Once done, remove plastic disc and play music. It can cost only $5. Instead of reaming out the center hole, I would file down the bottom portion of the spindle. Of course, easier to do on turntables with detachable spindles. I believe a Frank Schroeder designed turntable once had a spindle like that.
There was a Nakamichi turntable that would detect the degree of eccentricity and correct it by pushing the record at the precise point to reduce or eliminate the potential wow and flutter. The center spindle was removable. Most of today's turntables have it permanently attached to the platter so you can't do the same even with eyeballing. Therefore it's either a $6000 tool which eyeballs it for you (after reaming), or you can do it yourself. I hope I win the lottery this weekend so that I can buy one. My Foreigner and KISS records will sound much better.
Warning, if you buy this device you will get depressed, because you'll realise that the majority of the records you own are not perfectly centered, which is a shame really, because there isn't a reason for them to be like that, thanks for the video.
Nice review. It was interesting to see if the audio recordings would clearly highlight how significant the “wow” would be present. Chad would be happy with this kind of tool if he does needle drops again, if not already used it. 😎
They’ve said on other forums they aren’t lasers, they’re LEDs. I don’t see how anyone who’s spent a significant amount of money on a turntable or cartridge could not invest in one. As with record cleaners, the fact is that $10K or more in LP playback gear is dependent upon that piece of plastic you’re spinning, and even a $500K turntable/cartridge won’t sound right if the LP isn’t centered.
BTW - The "TOMMY" 1st press British LP that Michael played to prove records, if properly cared for, can last a lifetime. I remember watching a video( possibly on the Analog Planet channel) where you can see the record has been pressed off center. Even with no audio, you can see the tonearm swaying in and out.
Interesting device. My collection isn’t nearly big enough to invest in something like that yet. However it’s good to know that it exist. PS please do another room tour. I’m pretty sure you got a lot of new gear.
Yep! It's quite fascinating how "audiophiles" are so in love with such a deeply flawed format. Forever trying (in vain) to try to make their records sound as good as a CD 🤣 hehehe
@@trackingangle929 Which is very cool but some would say a detached platter is prone to resonance. It seems that while dealing with the issues of vinyl is fun and part of the hobby, it’s also like a never ending game of wack-a-mole. And now that we know digital can be introduced into the vinyl chain with very few listeners the wiser, can we still say there is a sonic need for vinyl (other fun aspects of the hobby aside)? A serious question, and I (and I’m sure others) would love to hear your thoughts on it.
Great demo! Oh how I wish I could afford one. This is something I'm so sensitive to, and it absolutely ruins the experience when encountered. I guess a reamer and my ears will have to do until the tech comes down in price.
I heard more of a difference on the piano recording. To be expected. Since I usually just eyeball records as they spin and correct them if they seem slightly off, I probably won't be plunking down $3,000 on one.
How did you deal with the washer that's part of the SME record clamping system? I don't understand how you were able to switch back to the SME clamp after the centering process, without messing up the correction.
The only difference I can hear is the decay of the notes. Without the adjustment the decay is not steady. With the adjustment the decay is smooth and seamless.
I can't believe how easy it is to hear the difference as there are so fewer beats between tones. They are more consistent.The tones with less wandering and variations The second correction is like the difference between and old puck driven table and the best DD turntables. What a difference. . What does it do with a warped record? Are you going to review the SME 60 and compare it to your Scandinavian turntable? This device could easily spoil you.
Alas. Somebody got to it. The biggest elephant in the room. My personal hate about some records. How can they put a man on the moon and not match side A and B vinyl stamps???? Been wanting to come up with a solution for years. Nearly imported a Nakamichi (the cheaper one) from NYC about 10+ years ago for £2k but it fell through. Then, was in a maker space making plinths and thinking up ways to centre reckurds but it closed down along with my attempts... Once put an AT platter vac topper on my Garrard 401 and could nudge the Vynolium until the headshell stopped moving. Fiddly but could finally bear to listen to the bad wonkers....
i bought an item called "center-disc" in 1994, it was all manual and did the same improvement as this device but for 99 dollars and use it to this day... you center it once and no need to do it again, a-bit-late, ... even half speed or direct to disc or any record need this done to improve playback, once heard, you can't go back.... yes - a-bit-late boys
I saw a demonstration of this item at a recent HiFi Show in the UK.....fascinating technology but MONSTER expensive for a solution that may affect on a fraction of someone's Collection - However, just like the early cavitation cleaning machines, this is likely to be a (relatively) reasonably priced item of the next five years or so....But are you going to invest in one yourself now Michael?
Hi Michael, from your demo and through my iPhone, it seems that given that the second record was MUCH more improved with the device than the first record, this DS device makes a big improvement on very eccentric records. But on mildly or perhaps moderately eccentric records the improvement is there, but not as great. Possibly marginal?
On a mildly eccentric record, only the innermost track or a sustained note would have audible error (unless you have perfect pitch, in which case you probably hate vinyl already! I have a ton of records that sound great up until the last 3-4 minutes and then the wow / wobble is obvious.
Did you happen to measure the diameter of the hole after correction? Just curious how much it takes... I noticed the pitch warble way more on the piano than the violin.
Wanna play a record? First, clean it using a vacuum. Next, check it's centred and ream out the hole. Then, anti-stat gun and brush. After that, place an outer ring and clamp on the record. Nearly there, clean your stylus. Now you're ready to play for 15 minutes until flipping the record and doing it all again!
I think the first record shows the value of this device, more than the latter as Oistrakh’s massive amount of vibrato makes it more difficult to discern. Would you be able to put higher res files up for download like you have in the past?
It took me a couple of listens before i got it. And that was because i was concentrating on differentiating. More noticeable on the 45. In a blind test compensated for "order effect", i probably would not have noticed, i would have just put it down to overtones from viola tremolando. In fact, i prefer the 1st drop of the 45. Maybe the composer should have scored tremalando fingering for the string soloist? I feel it gives the strings a little more presence. I guess im lucky in that i quickly get lost in the music. $6K luckier!
Very interesting issue I was not aware of so far. Would a outer ring like VPI and Transrotor offer it for many of their turntables help on this issue with uncentricity? They are precisely machined and should limit the movement of the vinyl and keep/force it more towards the ideal center of the plater or am I wrong?
It's the relationship between the spindle hole and the grooves that cause eccentricity. The spindle hole can be perfectly centered in the disc and still have this issue because the grooves were pressed off center.
So, to center a record you have to ream out the center hole so it is larger than the spindle? I wish it wasn't so expensive. I would buy one to center all my QRP pressings. I saw somewhere that there was a computer program that can sense and correct an off-center record. Thank you!
Linear tracking???! You'll frighten the audiophiles with words like that! 😆 Even though Revox saw fit to make a linear-tracker, most audiphiles would clutch their pearls and faint at the thought!
6 grand could buy a lot of records. But this device is certainly amazing. Hopefully they come down in price & are more widespread within the next decade or so! :)
Informative look at an interesting gadget (OK tool). But Michael, I'm concerned about you. Based on the last scene it appears you've stepped into the looking-glass world!
You can hear the difference but I have a question ? What is the position of the record after you have adjusted it and played it ? Yes I understand that the record is clamped or suction is used and this should help but has the record moved during playback
@Zockblatt Shickleblender In 2022, why do they press records off center? I return such records. Problem solved. This device should rather be used by them, not us.
Agreed, but is the improvement worth $6K? Not for me, i can live with a little tonearm sway. ed, but is the improvement worth $6K? Not for me, i can live with a little tonearm sway.
#1 it's nice to see that your records are as noisy as mine :) #2 isn't it too bad that you can't get a Nakamichi type turntable today that will take care of the geometry issue for you? #3 That second record is so bad that you would need to ream it out quite a bit.

Hi Michael, from your demo and through my iPhone, it seems that given that the second record was MUCH more improved with the device than the first record, this DS device makes a big improvement on very eccentric records. But on mildly or perhaps moderately eccentric records the improvement is there, but not as great. Possibly marginal?
That’s of course true
On a mildly eccentric record, only the innermost track or a sustained note would have audible error (unless you have perfect pitch,
in which case you probably hate vinyl already! I have a ton of records that sound great up until the last 3-4 minutes and then the wow / wobble is obvious.
One Word: WOW!
Why would I buy a turntable after seeing this?
Did you happen to measure the diameter of the hole after correction? Just curious how much it takes... I noticed the pitch warble way more on the piano than the violin.
But Michael, what happens if there is no ability to move the record on the platter to ‘fix’ the issue?
My thoughts exactly??
@@howiefeltersnatch69 I guess you use the reaming tool and widen the hole!
I bet that “eccentricity detector” goes wild whenever it’s pointed at any audiophile.
I shared that on my DS Audio FB group before it came out, I thought it was going to be $5500
Man O’ man, “throwing a record on the hi-fi” is becoming quite the process…. Nifty tool though.
Wanna play a record? First, clean it using a vacuum. Next, check it's centred and ream out the hole. Then, anti-stat gun and brush. After that, place an outer ring and clamp on the record. Nearly there, clean your stylus. Now you're ready to play for 15 minutes until flipping the record and doing it all again!
what happens with a record which is eccentric on one side, but okay on the other?
Just get a CD or stream. Humans are really hopeless. The age of music on plastic, augmented by digital devices, is truly decadent
Two thumbs up!
I think the first record shows the value of this device, more than the latter as Oistrakh’s massive amount of vibrato makes it more difficult to discern.
Would you be able to put higher res files up for download like you have in the past?
I owned a Nakamichi Dragon ct and wished i never sold it….
I dont know what kind of ears do audiophiles have to hear a bad sound from record who is displaced for 0,0002mm off the center..
Pitch sensitive musicians are more bothered by this…
Well, Mofi proved that their ears aren’t that good…
Great results. But that price!! Ouch!!
I think Darth Vader had one of these. He’s big into vinyl and correct setup/ tracking force.
Lol it's all about the "force"
It took me a couple of listens before i got it. And that was because i was concentrating on differentiating. More noticeable on the 45. In a blind test compensated for "order effect", i probably would not have noticed, i would have just put it down to overtones from viola tremolando. In fact, i prefer the 1st drop of the 45. Maybe the composer should have scored tremalando fingering for the string soloist? I feel it gives the strings a little more presence. I guess im lucky in that i quickly get lost in the music. $6K luckier!
Very interesting issue I was not aware of so far. Would a outer ring like VPI and Transrotor offer it for many of their turntables help on this issue with uncentricity? They are precisely machined and should limit the movement of the vinyl and keep/force it more towards the ideal center of the plater or am I wrong?
It's the relationship between the spindle hole and the grooves that cause eccentricity. The spindle hole can be perfectly centered in the disc and still have this issue because the grooves were pressed off center.
Have you ever tried using Green Stuff to fill in the gap so the spindle is centered?
So, to center a record you have to ream out the center hole so it is larger than the spindle?
I wish it wasn't so expensive. I would buy one to center all my QRP pressings.
I saw somewhere that there was a computer program that can sense and correct an off-center record.
Thank you!
What I want to know is how much does it cost?
$6K!!!!
@@robertjermantowicz8619 Then forget about it..
I can hear background noise with uncorrected.
pretty cool, way out of my price range though but I do need to buy a spindle hole reamer for sure.
Is there an option for us mere mortals, That thing cost more then any car i have ever bought.
Am curious if a linear tracking arm would negate the effect
Linear tracking???! You'll frighten the audiophiles with words like that! 😆 Even though Revox saw fit to make a linear-tracker, most audiphiles would clutch their pearls and faint at the thought!
6 grand could buy a lot of records. But this device is certainly amazing. Hopefully they come down in price & are more widespread within the next decade or so! :)
@Nicholas out of curiosity was hoping you could share your homebrew method
Informative look at an interesting gadget (OK tool). But Michael, I'm concerned about you. Based on the last scene it appears you've stepped into the looking-glass world!
WOW! Thanks for an amazing demo...........Too bad about the price.
I got Ortofon to make me a stylus out of King Tut's meteorite dagger he was buried with. Let's say the sound is, "out of this world."
This is cool!
You can hear the difference but I have a question ? What is the position of the record after you have adjusted it and played it ? Yes I understand that the record is clamped or suction is used and this should help but has the record moved during playback
@Zockblatt Shickleblender In 2022, why do they press records off center? I return such records. Problem solved. This device should rather be used by them, not us.
Makes my Mo Fi digital one step sound even more analogue 🤣🤣🤣🤣
A bit more noticeable on the higher frequencies?
Agreed, but is the improvement worth $6K? Not for me, i can live with a little tonearm sway. ed, but is the improvement worth $6K? Not for me, i can live with a little tonearm sway.
#1 it's nice to see that your records are as noisy as mine :) #2 isn't it too bad that you can't get a Nakamichi type turntable today that will take care of the geometry issue for you? #3 That second record is so bad that you would need to ream it out quite a bit. I think it's great that they make such a device. Good Video.
Another vinyl rabbit hole to go down. I'll stick to my CDs, thank you very much.
Weak
why didn't you show when you used the reaming device?
Needed both hands
@@trackingangle929 could have put phone on tripod or had someone hold phone , major point of product is part you didn’t show
