" One thing to check out a class D (or any amp) is that they have a good control when signal is near zero."
Not sure what you mean by "good control" when signal is near zero.
If you're talking about no noise or hiss, my Class D amp is dead quiet.
On the other hand, my early Class D PS Audio HCA-2 from 20+ years go did have a slight amount of hiss. It was enough to be annoying. These amps were initially shipped with very high gain (something like 30dB). PS Audio later reduced the gain a few dB which corrected the issue for most people.
