Some manufacturers intentionally add harmonic distortion to amplifiers because many audiophiles like it. Not to mention that most audiophiles are trying to judge equipment through speaker/rooms that have insane amounts of distortion. It is like trying to evaluate a photograph through a foggy window. Even with the very best systems one has to be careful. Then there are the effects of price and appearance on audiophile psychology, expectation bias and so forth. Put in a properly blinded situation I doubt any of us could reliably identify any of these DACs. What any piece of audio electronics sounds like, with the exception of amplifiers, is more a matter of psychology than anything else.
If measurements are meaningless, an audiophile's opinion in regards to sound quality is worthless...except mine.
