Perhaps , but very few people base their opinion on distortion spectra . The main attraction is gobs of power and small cheap package. I lost the notion of " wire with gain" long time ago and search rather for color and reconstruction of reality lost during recording process. Different strokes ...
If , by any chance, you find one at an affordable price , don't even blink before opening your wallet.

Everything easy on heatsink and transformer. Class d produces sound effortlessly. Anybody having long spere time to listen for hours feels defeated. Its a phycological question rather than topology used in the amplifier. Put on a good movie and you will see time fly, even with a half decent amplifier.
The performance of some legacy gear is still in the hunt. A pair of complete unknown 1980s Sony semi-pro amps rescued from recycle for bench use measure distortion below 0.002% dominant H2 with only a reduced H3 showing up to 5 watts min. Both of course rising moderately at the top end. Ironically it's nearly identical to my Class D Audio SDS-120 build based on an overbuilt toroid analogue PS.

That is a nice amplifier that I never have seen before. Any nude pictures!?
Of the amplifier, rdf. We don’t want to trigger dreamth.

Have I said anything bad about class d amps? The only dissapointment I had in class d was the 60k Devialet on 40k speakers...but it was the only class d power lamp I have ever listened to. Oh I firgot the active Barefoot monitor speakers...of their 800watts near field efgiciency i can't comment but the sound was right there.No electrostats, but clearly very good if not perfect. My phone and laptop uses class d chips snd sound ok for me...I bought some class d and t chips a month ago, but didn't finished the speakers...

It's a rainy laundry day, no problem on the first part. Very little information is available on this past the uploaded spec sheet and an owner's manual. A Japanese service manual is available online for the SRP-P450 model. No idea if they share common circuitry.
Glamour shots attached. It appears well made for its time. I'm tempted to bypass the front end balancing and stereo/mono circuitry and running it clean input. It would also seem strange if Sony hadn't leveraged a simplified version of this design for the consumer market.

Beauty. Take care to inspect the output relay as Sony used to use exactly the wrong relays for that function.
You have that habit to speak of class A with cup D, naughty man.
A dirty mind is a joy forever.
I finished my first class D amp (NC400) a few weeks ago and was really impressed at first but I know things need a lot of listening before one can assess it properly.
After the initial impressions I did think something was not right and read somewhere they needed a few days to settle and set them up in the garage playing bird sounds for a few days.
This turned out to be interesting and passing the setup a couple of times a day, it clearly did not sound right and it did not get better even after 3 days so I decided to try one of my old style amps (onkyo and rotel) to see if it was the recording (youtube, example below) and now it sounded "correct" imho.
There could ofc be a number of reasons for this including personal bias but it would be interesting to hear what others find doing the same test.

At that price you should have had the option to return those nc400 kits...
Your second problem is being honnest about an expensive item.You should have told everybody how awesome it is to make sure you sell the damn thing before it's too late...
