>but my understanding is that people who know what to listen for can tell the difference on a suitably powerful/nuanced sound system. Or at least they claim they can. I've yet to know anyone with any expensive systems who claims to be an audiophile who can actually pass an ABX test with any more accuracy than random guessing would have given them. Largely because they'd need superhuman hearing - able to hear things that are literally outside the frequency of normal human hearing. Not saying these people can't exist... just that it's extremely unlikely.
