Why no Class D integrated love? (from manufacturers)

Off topic, but I borrowed a Naim UnityQute2 over the weekend that I ended up really enjoying with my Harbeths. I get the Naim/Harbeth love now, even with an entry level unit no longer in production.
One thing I noticed when A/B’ing with my setup is that things sounded cleaner and clearer at a microdynamic level, esp at low volumes when streaming Tidal. My SMS-200 into Ideon Audio 3R into the Job amp sounds impressively clean and spacious, for a USB setup but I feel like the UnityQute2, with just ethernet going straight in and no USB in the chain had some sonic advantages that brought it closer in some ways to CD or CD rips on a server. Anyone else have this experience? Makes me rethink everything really.
We buy all these high end cables and reclockers etc to improve the USB signal when just eliminating USB entirely from the chain seems, in my limited experience admittedly, to be the simplest and best performing option. I'm now looking at all in one options as potentially superior for those doing a lot of streaming. 

Muti-inputs corrupt the signal to a degree and this is more noticeable with Class D
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.

@ Mr m,
Running the exact same Rogue pharaoh with NOS mullard tubes as yourself and my experience has been very positive also. No regrets here. 

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.

Cheers George
