Class d amplification

@vinylshadow 

When was the last time you listened to a newer class D amp?  If you can, try listening to the Atma-Sphere amp the OP was mentioning or some the newer Gan amps in the 2K and up price range.  You’ll be surprised.  I know I was.

Atma-sphere makes a very good amp. The designer is very smart. But I would still get a Jeff Rowland Class AB or Donizetti before a class D. Class D cannot outperform a great AB amp. 

AS Class D </= CA211FA, that is saying something!  🤔

+1 on AGD (Duets) and they are upgradable as the tech improves! I use them on DeVore Super Nines.

Before the A-S came out, I bought AGD Audions. 
The AGDs are very beautifully tube sounding but the A-S surpass them in transparency and bass. If you want to bi amp, the A-S are a very affordable way to go.
