That, and several others. I think the main reason for it is that the "required" specs only applied to stereo products. They never applied, under law, to home theater receivers. Multi-channel products dominate sales, so to speak. So, some of them simply faded away. Thank you for taking the time to contribute.

Please find me that article. I would love to read it. Thank you for your comment.

@@audibleeleganceinc One sec let me find where I was reading it and post it. Might be cool like you said.

@@audibleeleganceinc Ok so I cant find the article or possibly the thread that was discussing this. It was basically a discussion that amps dont need them because of their already high impedance ... and that most amps already have the buffer built in which is why they have the high input impedance. So I turned to ChatGPT to ask if most audio power amps have input buffers as part of their design and this is what it says: Yes, most home audio power amplifiers for music playback do have an input buffer as part of their input circuitry. An input buffer serves several important functions: Impedance Matching: It helps match the impedance between the source device (like a preamplifier or a DAC) and the amplifier. This ensures that the signal is transferred efficiently without loss or degradation. Signal Isolation: It isolates the input stage of the amplifier from the source device, which can help prevent unwanted interactions and preserve signal integrity. Noise Reduction: By providing a stable and consistent signal to the amplifier, an input buffer can help reduce noise and improve overall sound quality. Protection: It can protect the amplifier from any potential harmful spikes or irregularities in the input signal. These benefits make input buffers a common and important feature in the design of high-quality home audio power amplifiers.

Well, that's not been my experience nor that of many others. Pot luck?

@@audibleeleganceinc maybe. I mean until last year I still had a Proceed preamp processor (was used only as a 2 channel) which I sold. That has hell of a lot going on:). I tend to leave my gear on all the time so maybe them not being cycled on and off helps

Thank you for your kind compliments and contribution to my channel. Yes, indeed, it was a most frustrating experience with that era of Yamaha as I thought there packaging was outstanding. I wanted to love it but even that could not overcome it being a serious underperformer. It was like a Corvette with a 4 cylinder engine. Used Yamaha today is still fetching far more money than it's worth. Please do tell others about this channel and please do subscribe as well.

@@audibleeleganceinc Thank you. Far too many un-informed "audio reviewers" here on UA-cam. Nice to see one that actually knows what he is talking about.

@@daleboylen6427 well, I try to speak in ways that most people can understand. There will always be "interesting opinions" from sincere people and then, of course, there are the trolls who are pretty easily spotted and disposed of. Once in awhile, to my delight, I am, myself educated by folks here. I gleefully tuck that away for future use.

Thank you very much for adding your comment to our channel and the information provided is most interesting and useful. Please tell other about my channel and subscribe if you have not done so already.

Ultimately, Nelson is correct and I have heard some of his products. I can recall years ago when Rotel upgraded their venerable RA-840 integrated amplifier to version 3. The English press simply ripped it apart as garbage. Not withstanding Rotel's assurances it was good, it lasted 8 months and was replaced by the version which crushed V3. Same parts, different layout. Naim audio often played around with the shape of tracings on a board right along with where the parts were located on it. Audiophile Systems, the original importer of Linn products, distributed a lovely guide called "Specifications and Other Nonsense", I copy which I still have today and make copies for some who are willing to have an open mind. It really comes down to "How does it actually sound?" and that's it.

Thank you for contributing to the channel. I suppose there are situations where somebody accidently got it right and, of course, there is the general resolution of the entire system itself. The better the system, the more that can be revealed either good or bad. So, an interesting observation assuming you are listening to music musically and not simply tonally. Thank you, again.

For starters, watch all the videos, particularly the LP12 from hell series. While it does not apply to a stock LP12, some things will prove useful. Then, watch the LP12 from Heaven. That one was a beautiful stock table. Thanks for commenting. Most appreciated. Good luck with fond memories!

Differences can only be revealed in comparisons between active and passive. I can not comment as to your observations but if you are happy, well, that's the goal. Thank you for taking the time to comment.

Thank you for taking the time to comment. I appreciate the effort.

Thank you for contributing to my channel. I appreciate the effort. Please tell others about our site and please subscribe.

That has been my experience and every time with streamers. As I said, years ago I played with passive preamps and had pretty much the same experience.

Well, very expensive tires will likely improve the performance of a heap of trash car. However, you will not get the total benefit out of the cost of those tires. They are limited by the heap of trash. Same basic principal. It's about getting the maximum performance for the least amount of dollars, really.

Keith, I often make fun of the audiophile terms because if you used them in a conversation with musicians they would likely have 2 thoughts. One, what drugs are you using and where did you get them because they want to avoid that seller, or: Two, just the opposite as they want to become as delusional as you. Mind you, those ill-defined terms, with no real reference in reality, can be somewhat useful, I suppose, but only after the musicianship has been proven by the equipment. Otherwise, you are spending a lot of money to hire a wedding reception band to be in your home. By the way, for years in the 90's the buzz term as "Midrange suckout." Still pondering that one to see if it would help me clear out toilets.

@@audibleeleganceinc Yes and to your point, I've never really grasped the audiophile vocabulary.

Thank you very kindly for an equally informative response. Having just received the Rega Naia turntable, I'm not quite sure what else a $40,000 LP12 can bring to the table, so to speak. While the Naia is not inexpensive either, I wonder with Linn and other companies if the pricing is not so much performance as it is pricing to establish the exclusive "you have arrived" marketing concept. To make matters worse, in my observations, like many "vintage" products, the prices have been sucked upwards for really no legitimate reason other than the price of new similar products has been inflated. The concept of "just like" really does not work when you consider 20 to 30 years of wear and tear along with engineering improvements. As for tables in the 4K range, I will go with your opinion on this as I have not heard a new Linn LP12 in years.

Ah, machines don't read. Nuff said.

@@audibleeleganceinc Lou, are you okay? I consider AI a machine. And it sure can read!!!

@@zizendorf Do you really think they use AI on conveyor belts or the dump bins used by the post office? Or that loaders or delivery drivers give a shit?

@@audibleeleganceinc No, I don't but you stated machines don't read and many do. I get confused sometimes with your strong opinions. So, how nicely are those Rega TT's treated?

I have seen have so much nonsense over the years, contrary to the "party line" that I have an actual basis for my views. I am known for my passion about things and I pity those who follow dispassionate advisors.

It is simply amazing! Two of my employees already want to buy one.

​@@audibleeleganceincIt is good to hear Rega is living up to their reputation as opposed to burning the brand.

@@johncrockford4216 that's because they are still owned by the same bunch of people. It's that simple.

​@audibleeleganceinc True. The ownership is the same and they are not controlled by bean counters influencing the bottom line over quality.

@@johncrockford4216 And that, John, is far more true than you realize. I am struggling with just such a decision about a company that I have represented for 39 years while witnessing another company we once represented traveling down the path to no worthy end after the death of its founder.

That's why I posted a sort of "heads up, folks." It is even more of a disaster if it still has the original shrink wrap on it.

@terrywho22 Interesting... as we're in the midst of a heat wave right now. Just had an album delivered. It was left on my concrete front porch. It was packaged in a cardboard box and inside of that what another cardboard album box. It wasn't delivered by USPS. The box was cold to the touch, as was the inner box. The delivery truck has AC.

@@zizendorf Glad you got to it quickly!

And if there is still shrink wrap on it, watch out!

Shrink wrap in the heat. Yes, a klingon!

Absolutely correct! Vacation mode means almost everything gets unplugged! Thanks for your contribution.

Thank you for contributing to this channel. I appreciate the effort. Please do subscribe and tell others about my work. Thank you, again.

As I said to another, distance can be a critical factor in what happens during shipping. By the way, marking a package Fragile actually increases the risk of damage. Great article about that in Popular Science.

@@audibleeleganceinc For me, it matters that I trust the folks at Rogue Audio. They provide outstanding customer service and are never too busy to discuss products! You actually get to develop a "relationship" with their personnel who are typically quite talented engineers. It's why I'll stick with them.

@@zizendorf And that's why we happily sell their great product!

@@audibleeleganceinc Excellent! And that's why I extol your virtues when I chat with them. Just Good People!

Some might challenge that the VTA can change the sense of timing too, which, I agree with you it does. No, the thickness did not appear to be any different than the standard Rega mat. Many people do not listen for rhythm, pitch first but go to tonal emotion as their guide. Well, a great singer with a lousy band is not a great experience. So, it's hard to explain this without a bit of personal interaction. I teach this and many customers thank me for it. I have already done videos in our catalog trying to address this approach and to give some basic guidelines. So, please check them out. I sincerely can not repeat this topic again and again as I have some really critical problems going on with my wife's health. The final point being, simply listen to it and not the words written by a reviewer who claims this or that about any given product. If it works for you, and it can, great. However, do not simply assume that anything commercially promoted is not without bias or intent.

@@audibleeleganceinc good luck to you and your wife. Thanks for the recommendation. I just looked at your video history and put a bunch of them in my queue.

Thank you kindly for contributing to my channel. It is sincerely appreciated. Every once in awhile, I just can not resist the opportunity to be animated to get people to both think and remember what they are doing. The only company that really listened to what they were inserting was Naim Audio under Julian Vereker. Yes, they were their transistors and what they were checking for was noise.

I could not resist doing it and it was in front of a customer who did ask that question. I just wanted to drive the point home and sometimes I can be really spontaneous. I have had experience with "matched" tubes and when I put them in they rang like all hell. Now, was the seller dishonest? Maybe, maybe not. However, I am quite familiar with the gods of conveyor belts and know quite well people are to knock blocking packages off the belt and let them drop 20 feet. My son almost took a job doing that at one of the hubs. Likewise, when parcels are shipped USPS, they all drop into big dumpsters and heavy items may come crashing down on light ones. So, to be honest, it's reality.

@@audibleeleganceinc . Yup, all true. Well, at least I think so.... Acid Jazz, Funk & Brass 🔈🔉🔊

@@TriAmpHiFi Well, I hurt some audiophile's feelings and they unsubscribed. I'm sorry, but after 40 years of experiences, I just am simply going to tell the truth whether it makes people uncomfortable or not. It's just the way it is.

@@audibleeleganceinc . "Living Well is the Best Revenge"

I’m never buying another matched set of tubes again 😢 this week anyways!

Well, if you can not, then you should not be driving. In actuality, you can if you are paying attention to the music. You can still hear timing and phase which is essential when driving when you hear a car coming into your blind spot or falling back. That can also be pitch. So, while we both are losing frequency range, the critical areas remain fairly untouched for our survival. Nature is pretty cool. So, while we might not hear a twig being broken by a predator, we can still hear someone yelling "watch out!" That's the primary range of music. Look at the Fletcher-Munson curve and it will all make sense.

Your experience is what is called leaching. Many clear covered cables experience this. However, in the case of the OMC500, it also leaches into the actual copper. Many others cables have the copper insulated in a non-clear jacket. Thank you for contributing to our channel. If you have not subscribed, please do and also tell others about our work.

Yikes! Didn't know about them but the clear jacket approach was made popular by Monster and so there being look-a-likes is not surprising. Thank you for contributing to our channel and please do subscribe. It would be great if you told others about our work.

Outstanding contribution. Thank you for taking the time to contribute to the channel. Now, I don't know if the cable used by manufacturers is exactly the same or subject to the same issues. All I am suggesting is take a look at them if you have cause to get into you speaker. I don't want people taking their speakers apart as this could create even bigger issues.

Thank you for your contribution to this channel. Yes, another person has reported their use as well but, again, I don't want people taking their speakers apart just to look as I don't know if the wire used by them is different than the OMC500 issues.

Thank you for your contribution to the channel and you are the first to report that you did, in fact, find green cable inside a set of Klipsch speakers. Now, changing the cable to another brand will also have a sonic signature impact so I don't know exactly what improvements would have happened (in comparison to the Mogami) if it had been rewired with Monster Cable. But yes, you can hear the difference. If you have not subscribed, please do so and tell others about this channel.

Yep, that's usually how it is discovered. That's why I suggested the people take a look. Thank you for contributing to the channel. I do appreciate the effort. Please subscribe if you have not already and tell others about our work.

Well, hopefully they turn out delightful and you can continue to enjoy your music.

As did I! It's almost the worlds largest alumni association! I really try to break things down to terms folks can understand. I usually use analogies. Thank you for taking the time to comment on my channel. Please subscribe if you have not already and tell others about this channel.

Thank you for your contribution to the channel and subject. Any contribution to explain what is happening is most acceptable. That said I know chlorine is in play as it and the plastic leaches into the copper.

The moral of the story is to check all turntable bearings. At least with Thorens you can do that and given they were very popular in the 70s and 80s and are fetching very high prices, they are game. You can not check the bearings on any direct drive table which is why I won't touch them.

Heat and electric cars are going to change even your world.

@@audibleeleganceinc Are you talking about my electric bill? My home is all-electric. I’ve already have seen effects of climate change in my electric usage, specifically in the winter. Electric cars, are going to affect me how?

@@zizendorf Well, we produce only so much electric. New England gets their electric from Canada. Add electric cars to the load. Heck, even California has asked people not to charge their cars so they would have electric for air conditioning.

Thank you for taking the time to add your comment to our channel. If you have yet to subscribe, please do and tell others about my work.

Yeppers. Oh, you can really hear the relays on some vacuum tube equipment really chatter when it hits around 100 to 105 volts..

Well, I am not speaking to that or, for that matter, any other cable or product. I do recognize, however, that many cable companies do not, in fact, own the means of production. They have to pay someone to make them for them and there are different companies that do that Costs are both a combination of the complexity of the cable itself as well as the set-up costs which gets averaged out over the size of the run itself. The more unique and small batches simply cost more.

Oh, yes. My staff just toasted a 70s receiver that had not been powered in years. 120V hard start with a power switch. I have covered how to use a Variac twice on my channel. Do a UA-cam searcj of my channel and you should find it easily enough. However, you can start by opening up the unit and inspecting the capacitors themselves. The large ones are the power supply caps. IF there is ANY bulging of them at their ends, they are done and any powering up may toast them completely.

The green is deterioration of the copper. The deterioration creates diodes and resistors. It will work, yes. Work at spec, no. I'd replace it with new. You raise a slightly interesting question about moisture as that might be a common thread although the last cable section I dissected the inside of the clear jacket was an oily type goo. That's not moisture.

I've experienced that goo too. I assume humidity acts as a catalyst between copper & chlorine. Is there an online paper on the deterioration into diodes & reduction of copper cross section (resistance)?

@@trevorbartram5473 Not that I am aware of other than a fairly old article that I read years ago when this was first spotted. I don't have that paper any more.

Jay, thank you for taking the time to contribute. I'll be repeating an earlier video about buying hygrometer to measure humidity in your room but it was more targeted towards winter when the heaters are running and drying out the air. I used a Zerostat for awhile but could never really get the full benefit of it.

I'm probably over zealous in cleaning my vinyl.

@@jaycoleman8062 Oh, I don't think you can unless you reach the point where the process of playing a record undermines the enjoyment of listening to it.

Absolutely, it is just a routine I have. Music is still #1.

ah, no but also see next video on this subject.

I am glad that you have also reported this happening and that other pieces have not. A manufacturing consistency problem? In any event, I am not telling people what to buy but simply to replace it. If you want to buy OMC500 again, fine. Any cable that is deteriorating like this needs to be replaced. That includes lamp chords or anything similar.

Thank you for confirming, like others, that they have had this happen. All I am telling folks is if their cable has done this, replace it.

Tom, I don't have any of that new around here. That's why I put a penny on the video but it was not well shown. Tomorrow's recording will cause a panic as a major speaker manufacturer used this cable for internal wiring. Now, some folks have not had this problem and there are others who have. We will do more closeups tomorrow.
