I am an old audiophile and must admit to being suspicious of this completely new class if amp when released, particularly as they a flea weight.
When first released there was a lot of hype about perfect sound and then a collapse as everyone realized they just didn’t sound that good. Then year by year they got better sounding. I have heard some contemporary Class D in my system. They can sound very good.
But the thing is, it depends on exactly how much you have to spend, your musical taste and system. Say you have $X to spend… maybe there is a class D that would be the very best sounding amp for you… but had your budget been $2X then some class AB would have been the best for you.
So, I would not stay clear of Class D. You need to carefully audition any high end amp to be sure it has the sound you want and fits in with your system.
