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

I use Class D Audio for center and surround speakers. They sound great in that capacity. I have another Class D amp with upgraded power supply and two modules bridged for mains, it sounds very good, but I haven't used it for months now since my 3C24 amp came on line.

The 3C24 has much lower sensitivity than the Class D, so it's used every day now, so I don't have to adjust my pre-pro (Arcam AV-9) mains channel every time I use my HT system. It sounds great, and at 73 YOA, I figure why not use and enjoy it at all times?

Regards,
Dan

Amps based on the PuriFi modules have received glowing reviews. One example is the NAD M33. There also are some small shops assembling amps from PuriFi and other components. Nord and Apollon are two.

I'm pretty sure that 6Moons really liked the PuriFi demonstrator amp. I find it difficult to follow their reviews, between gobbledygook, constant reference to products I don't know, and tiny paragraphs of text sandwiched between huge ads.

There is only one so far that has taken Class-D and it’s operation to the technology edge, that "could" even better the best Class-A or A/B’s.
And that is the Technics SE-R1 that uses linear power supplies, the latest GaN devices, and has taken their "switching frequency" nearly 3 x higher than any other Class-D’s have so far, which means 3 x far less switching frequency residual noise and all important phase shift at the speaker terminal outputs.

This 55kg monster has taken Class-D technology to the limit "for now."

I am waiting for Ralph Karsten's Class D amp to become available.
If anyone can design a good amp, it is Atmasphere.
