??? Our aim is the same as yours. We want maximum enjoyment out of our music and want to optimize our gear to get there.
This neatly encapsulates what some may perceive as your apparent myopia, and the associated problem that many have with ASR. If you believe that the above is truly a shared goal, then why on earth would you insist that better measuring components necessarily produce better sound?
Do you really imagine that those countless audiophiles who derive immense enjoyment from tube amplifiers, or Nelson Pass amps, would somehow find even greater enjoyment through the use of amps with lower distortion? Do you not understand that many, if not most of them, have spent decades optimizing their gear for precisely the purpose that you mention?
Pass, as you probably know, conducts listening tests on his new amp designs, the results of which have typically led him to intentionally introduce some distortion. In other words, a high percentage of listeners in those tests preferred the sound signature of the amps with some added distortion.
I think that part of the problem is that you, and many objectivists, conflate "best sound" and accuracy. Yes, you might reasonably argue that components with the least amount of distortion are more likely to reproduce recordings more accurately than those which introduce some distortion, but to then assume that such sound is necessarily "better" is a dubious leap.
