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

No all regulators do not have "a sound". Circuit implementations have a sound. Even a properly implemented low cost 3 terminal regulator implemented properly will be sonically transparent.

So what you are saying is NO you don’t have measurements. So pure is just your personal taste, not an accurate unbiased assessment. Thank you for clearing that up.

At an electronic level pure can be measured. Given you have no measurements your claim of pure is only that, a claim. You feel it is. I may think it sounds more colored.

I am judging. Too many audiophiles claim to be seeking sonic accuracy because they tweak this or tweak that, meanwhile their listening space is a disaster and they have more money into cables than their speakers.

There are so many highly experienced audio pros in this thread that I still get a little overwhelmed by the technical talk, specs, etc. So after reading all the responses, here's what I'm thinking---so I have a pre-out on my Luxman 505uxii integrated and I have a pair of power hungry Dynaudio Special 40s. I am thinking of adding a class D to help the little Dyns and this is why I started the thread. Between looking at the Dynaudio S40 specs and the class D specs, I'm not sure which one would be better (or all of them). Let me know what you think. Also, I've never tried monos so that sounds interesting (budget is < $3k)
1. D-Sonic M3a-800 s (stereo or mono)
2. Wyred 4 sound ST500 Mii (stereo or mono)
3. Nuprime ST-10 or ST10M (really looks interesting)**
4. Bel canto REF500s
5. Red Dragon S500 (all sold out for now but Ryan at RD emailed me and said the Mk3 will be coming out in Q1 of next year---COVID has slowed everything down)

All have great reviews. I think all of them have 3-5 year warranties and pretty good customer service. I appreciate your thoughts and suggestions.

You should really add these to your list.

Also, take a look over at AudioCircle; there are a number of active forums from Class D manufacturers and a variety of other threads.

The Luxman is more than enough to drive those speakers.

Just look at the impedance/phase curves, absolutely no problem for the Lux, and it will sound better that any class-D on them, to boot.
