High end Class D amps?

Just an observation and a question. Are there 'high end' Class D amps out there that are just as good as Class A, A/B amps? I realize that's a sensitive question to some and I mean no disrespect---but whenever I see others' hifi systems on social media, all of the amps are A or A/B. There's always Pass, McIntosh, Moon, Luxman, Accuphase, etc. Where are the Class Ds? For folks out there that want more power for less efficient speakers and can't afford the uber expensive Class As, A/Bs, what is there to choose from that's close to those brands? Thanks

@georgehifi -- It doesn’t matter. It puts out 500 watts into 2 ohms. That’s enough for most users. I consider "doubling" an irrelevant factor. Does the amp generate enough power for the intended use? If so, it’s a good choice (as far as power goes). If not, it’s not.
By the way, your statement is logically equivalent to saying that if an amp does put out 500 watts at 2 ohms, it is somehow lacking if it provides more than 250 watts at 4 ohms or 125 watts at 8 ohms. Why should that be a problem?

George does not understand class D and even though I have tried to educate him he refuses to learn.  I expect some statement now about EPDR. It will be wrong.

Then next you lot may as well just tell us to use this 6000watt!!!!! Class-D Behringer for just $600us.

Let me tell you, that on the Wilson Alexia in an a/b it was trounced by the 40 x times less powerful!!! Gryphon in dynamics and bass control. The Behringer was thin, anemic, weak in the bass and sounded like it was struggling

I didn't say that; I didn't say that all amps are equal, nor that they sound the same, nor that they are of the same quality.

I did say that I fail to see any relevance to this "doubling" business that has become an audiophile touchstone. Those who claim it is important seem to resort to pseudo-technical handwaving. Maybe there is a reason, but I've never seen it laid out in valid technical terms.

And YOU didn't answer MY question: If an amp can put out 500 watts at 2 ohms, why is it important that it put out no more than 250 watts at 4 ohms?
