Last year I decided that I really did not like Class D amps. I have listened to them, but they are just too clean -- they are extremely clean, but they just did not reach out and grab me - it was just not emotionally engaging. I did not get excited listening to them.
However, there a couple Class D monoblocks you could look at. These have discrete Class A input stages which will make the amps more rich sounding and engaging. Keep an eye out for a set of used PS Audio Stellar M700 monoblocks. You could also look at the Nord One Up or One Up SE monoblocks. Choose the Sparkos op amp for this as it is definitely a warmer/richer sound. I use Sparkos op amps in both my DAC and line mixer from my computer system and they are awesome sounding.
