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

If speakers should strive to be efficient why shouldn’t amplifiers? Efficiency is always a good thing. 

Even worse, efficient speakers tend to be big heavy and bulky. Efficient amps the opposite.


Evidently, it was too much to hope for some reasonable discussion of the virtues of the Apollon, with perhaps some owners of competing brands like Nord and March contributing also.  But so the 'gon goes.
I have a March Ncore P502. It's a very neutral amp which to me is the best thing you can say about an amp. Never heard an Apollon but they measure very well and inside they look tidy and well laid out. 
If you think of the number of people on the planet, who are audiophiles or enthusiasts, and among those who own speakers whose impedance dip to less than 2 ohms - that must be 0.01%? Don't know. But for the rest of us folks the Purifi would be more than sufficient.

Would love to hear from other Purifi owners experience who own Nord or March.

I had a HCA-2 and still have a PSAudio GCC 250 (moded as new by Chris Johnson) that I bought when it first came out. I then had several W4S models > Emerald Physics 100.2 SEs with upgraded fuses > Audio Alchemy DPA-1> PS Audio M700s, and now, and for the foreseeable future, my awesome EVS 1200, though I am still in line for the Voyager GaN


Stereophile has a very nice review of the $2500 Marantz 30 integrated
