Seems to me we've come pretty far, and that there really is not much point to continued debate, at least in some respects. Dr. Art seems to have conceded that his statements regarding the Bada, and related statements regarding tubes vs. solid state amps, are his
opinion, based on
his experience. Thus, they are necessarily subjective. Therefore, all a meet or individual comparison is going to reveal is that the reviewers either agree or disagree with Dr. Art's opinions. I think it is safe to say that many will not agree, just based on the different preferences that folks have, and based on their own experiences, etc.. This is no reflection on Dr. Art's opinion, necessarily, although I suppose there may be a question about whether his experience is broad enough to give his opinion any real credibility (just as there may be a question as to whether the conditions the reviewers evaluate the amp under are as good as the conidtions udner which Dr. Art evaluated the amp). But the fact is, he is not going to change his opinion just because others disagree with it. And we no longer really need to address whether the Bada is the best headphone amp at $450, $2000, or any price, or whatever,
for every person regardless of their system or preferences, because (besides being patently absurd), it does not appear that Dr. Art really meant to make this type of categorical statement, but merely as his view based on what he hears, what he has heard, and what he likes. He was just misunderstood because he tends to state his opinions in an absolute fashion.
Thus, while it seems it is still a worthwhile effort for some folks to evaluate the Bada to see if it is any good and whether it is an amp that forum members want to consider ("Knowledge is Good" - Animal House (1978)), it does not seem that we need to obsess any more about whether Dr. Art is "right" or "wrong," or whether anybody else is right or wrong, or whether anybody needs to "prove" anything as these are all just matters of opinion and people should take them as such.
