@johnk Has a point. It's not about the technology, it is about what the market will bear.

This is kind of my point. If you insist that a PASS is the very best (which you may) then no matter how good another amp sounds, if it is different, it won't be "as good" to you. So this "when will amp X ever be as good or better than amp Y" is kind of a setup.
From my perspective, having heard a nice, full Pass set-up, I cannot justify the spend vs. my Class D amps based on sound quality alone. Nor do I have the room or electricity budget! :)
My point is, Class D is very very good. Anyone waiting for Class D to reach "high end" is just not being objective. It has been there for years. If you want it to sound like your peculiar flavor of amp, well that's another thing. Yes, I have my own particular peculiarities too! :) I'm just saying, the wait for excellent Class D has been over for a while, but I must resign myself that my B&O powered amps will never sound like a pair of Conrad Johnson Premier 8, which you should all bow and worship... (hahahaha, j/k, but it IS my fave all time).
In any event, always make yourself happy with the money you spend.
Best,
