I have no problem with high end gear. I do, however, have a problem with some of the explanations that are given for why the stuff sounds better, and how the fact that it does sound better is determined. It’s OK to say nobody has a clue, which seems to be the case much of the time. Maybe it’s a trade secret. Maybe it’s some unknown physics. Maybe it really doesn’t sound better in a blind test but works on the mind somehow when you see it and know the story behind it. I’m of the mind that if there’s an audible difference it will be easy to measure if someone gives it a decent effort. Stuff that sounds different measures different. I’ve never experienced anything contrary to that. I'm not talking about how an individual component measures on a test bench, but the actual results that come out of the speaker from the entire component chain. I'm pretty sure that some components like DACs might measure perfect on the test bench but then do something "interesting" when connected to a pre-amp, which causes the end result coming out of the speaker to be noticeably and measurably different.
What I'd hope to see from high end gear is a relative freedom from issues like that. My idea of a high end DAC is one that is stable and accurate even into difficult loads, although it shouldn't ever have to see one because it should be hooked up to a good pre. It would also be exemplary for ease of use, good looks, robustness, and reliability. I think a lot of high end gear meets all my requirements. But so does stuff that costs a lot less. So it leaves me scratching my head over why the price gets so high on some of this stuff. It seems there's a little alchemy involved with intentionally going "out of spec." to produce a custom sound. Similarly with coffee, above a certain price point there's no more quality to be gained. You just get into specialty flavors from rarer varieties. Not inherently better, but definitely different.
