4 Ch Amp recommendations?

A good ear can easily hear the difference, most class D amps have poor S/N ratio and channel separation which is the reason they are typically used to drive subwoofers.
They are incredibly efficient and that is a plus but at the sacrifice of sounding kind of stale and lifeless as compared to an equivalent class A/B amplifier.

We all hear and interpret things differently though so YMMV.

whatever dude. You must have great ears. And they are not incredibly efficient when you push them very hard. But I won't get into debates on the forum.

If you're looking for the best SQ as you say, ditch the rears and bi-amp the fronts.

Well some car audio magazine reviewed an Xtant full range d class amp(put it on the bench too) and THEY say it's on par with some of the best AB class amps. So it's so subjective as much as factual.

It seems ICE power technology has made a huge difference
