You need to pay attension, read the right material, AND, stop trying to cross correlate one area of hearing to another: vinyl rumble to distortion levels.
You need to get out and do some research for a change on what is audible and what is not audible, specifically distortion. But then I'd rather talk to the brick wall, at least something sticks to it.

"Just detectable distortion Level" James Moir, Wireless World, Feb 1981, p32-35

"Audible Amplifier Distortion is not a Mystery" Peter J. Baxandall, Wireless World, Nov 1977, page 63-66.

"Ten Years of A/B/X Testing", David Clark, AES print 3167, 1991.

No, I will not tell you what is in there. You hunt and find out. But I doubt you will. Why would you? Your world may be turned upside down.

Just curious but you blast 300A's sources because they're old and then you use an article from 1981, 1977 and a 12 year old article to support your claim. How old is old and why is his 1977 article to old but your 1977 article not old and out of date. Or is that you just pick and choose what you like?

DBT does not prove A and B sound the same...says it right on the ABX site from Oakland University. What it shows is a correlation that people can't distinguish, (accurately) a difference within the testing environment with the specific people under test on that day. There is no support for audible differences under that test in that test environment. If that were enough of a proof Yorx would advertise that their $45.00 amp is indistinguishable from 70k Krell Mono-blocks. Jeez I wonder why all those smart engineers working for all these low end companies have not caught on. Afraid of being sued...if they were right they would have no need to worry - only Krell would worry. Unless of course the test isn't 100% viable --- Ahh that's true isn't it.
