My experience [and my knowledge of Statistics] told me that when there was common conception/perception about sound from many people it usually is "true" [true to me as I use my ears to prove it to myself]. But of course, if you control the bias, even JLH amp will sound similar to Gainclone [but that's not the point]
I have many OS DACs for example, and without bias or prejudice I don't play them often because they tend to sound unnatural and "miniature". Of course there are many other OS DACs that I don't own/listen but the point is that many observe the same perception. I'm not saying that NOS is superior. I'm saying that they sound different and one can be better than the other depends on the music type.
If you want a bias free or controlled listening experience, you can provide recording of NOS vs OS using the same chip that I can ABX. Mooly had done this and the result was so different that I can do 100/100 of Foobar ABX test if I wanted to.
The main result of such test for me was not knowing that they sound different but knowing where and how they differ.
So Sony should use dropbox for their petabytes of master tapes? Amazing that they didn't think of that.
I'm not trying to quote a complete statement, as Joe has not mentioned complete statement. Otherwise, it will be like reading his mind. I'm only saying that he related the post DAC issue with jitter, as everyone can read on the other thread.
I couldn't say if there was fundamental misunderstanding of jitter from a few words mentioned (e.g. by Joe on the other thread). I will be able to know if there was misunderstanding or not only if I read pages of words.
But by deduction method (including may be a little prejudice, but imho valid), it seems that Scott and SY were able to tell if there has been a misunderstanding of jitter.
Despite the facts there are still a minority that believe a full analogue system is better than a digital/analogue system...
And then there is the proliferation of digital myths that are appearing and have been doing for quite a while, my favorite is adding a clock on a long wire on an external PCB to improve jitter....

A lot of people think this is a smoky theory but it is not silly at all! (and it work very well !!):

quote from kusunoki "[FONT=Arial, Helvetica]My method substitutes the Chebychev filter with human ear's intrinsic "filter function," and this is the method's distinctive aim."
Right.. not silly at all.

They should use archive.org, it's good enough for the Dead head tapers. It even has my old website from 15 years ago.

My '68 chevy uses the bored out big block with Big Joe carbs, a modified Virtuoso Header. The tank is full of Grandpa's homebrew high octane juice. The plugs are gold plated and gapped to within a micron. The chasis rests on a set of slicks, the 'shimmy' on the bumps is well controlled and the volume in the room is bloody loud.
There is clearly losses in the 2015 Tesla version compared to the Chevy version, Of course I cant conduct this comparison for you, but the Chevy sounds pretty good to me and I'm curious what others will think..

Bruno Putzeys (the man behind Hypex amps) knows a lot about class-D amplifiers and power supplies. Yet, to a great extents he understands the subjective audible limitation. For example, the amp should be very low distortion because the distortion from switching amps is not ears friendly. He also found that the switching supply tho having good DC characteristics, the effect to the sound is also not good (EMF?) and his solution is a capacitance multiplier.
Clss-D amps... DSP... or switching supply versus linear supply is not so different with digital versus analog...
Bruno's Mola Mola DAC, was designed to be the best in the industry. He said it undoubtedly outperformed a top quality analog. I believe this. There's no way imho an analog can be more preferable when compared to digital that is designed with great care.
But when he compared his product with his competitor, he found his product has less preferable lower mid. It was not known what was in the recording, or which one was truer to the source, but IMHO he and everyone has to accept that at this level (i.e. quality recording) we need enjoyment more than just hifi.
I think the bottleneck in the Mola-Mola is the DSP and the switching supply... And its quality is far above what average of us have at home... And when people ears are very sensitive to fatigue (not all people of course), analog will probably be preferable.
So even then I'm not too surprised if people preference will still differ...
