I’m very fond of the heavily modded Trends TA10.1 I use in my main system. With a nice linear power supply, it sounds marvelous driving the 500 to 20KHz range in my trip-amped, very high sensitivity system. If you don’t need much power, that TA2024 chip has something magical, somewhat closer to SET sound than the vast majority of other class D amps. Swap a few passive components inside, by-pass the volume control (there's a switch inside on the pcb), use it with a nice preamp and feed it some clean 12V, it really is lovely.
I have zero experience with the higher end, more modern offerings but have a few small class D with various chips, some of them using great components, but they fall flat on their face compared to the old Trends amp.
