Why no Class D integrated love? (from manufacturers)

Unless I'm mistaken, it seems that Class D integrateds are not receiving the same attention from manufacturers as a whole. Sure there are the Peachtrees and NAD's of the world but by and large it seems the better class D tech is going into separates right now and that's somewhat disappointing to me. It's easy to find affordable separates based on the latest Icepower and Hypex modules but almost impossible to find integrateds based on anything but the lower end modules, for example the Nord integrateds.  Perhaps I am missing something? It just seems like this is an area that is ripe for some innovation. Anyone making "affordable" integrateds based on Hypex NC500 or IcePower AS1200 for example?

Now why exactly do I want to show distortion graphs?

To prove your hearsay.

Because your the one that said
"Muti-inputs corrupt the signal to a degree and this is more noticeable with Class D"

Granted multiple inputs and the switches to do it do, create more distortion than just a single input with no switches.
But it stays the same feeding either solid state Class-D or a solid state Linear amp, to say you can hear it worse into a Class-D than a Linear amps is just plain BS.

I’m not a fan of multi input devices period for purist listening, they’re noisy.

Sorry, but nothing you said gives a technical reason for you to say: 
"with multi inputs, a solid state Class-D is more susceptible signal corruption than a solid state linear amp is"
If you still believe this please show some distortion graphs proofs of both situations to explain to what seems to me to be a furphy.

Muti-inputs corrupt the signal to a degree and this is more noticeable with Class D because of it's purist design.
Please explain this in a more technical way why it is more susceptible to solid state Class-D than solid state linear?

What were the amps that had GaN technology in them?
Who did the private tests, can he comment here?
What was the amp compared to?

What worries me is down the road , these Hypex and ICE type modules will be no longer available for repairs like in the early Audio Research digital amps.

Yes even now many techs will not try to repair them down to component level, as they are very congested with smd (miniscule) parts, and the pcb's (printed circuit board) itself can be two three or even 4 layer designed which make it impossible to trace a fault.

Many techs I know now, just say throw the whole module out and put a new one in, if it's still available!!, if not the amp becomes junk.

Goes the same with just about any linear amp.
