I am a BIG fan of class D amps and I recommend them to everyone. Small, low power, fantastic sound (everywhere, but especially the bass sounds incredibly precise) and dirt cheap.
Indeed. Only sensible way to do things in the 2020s, for both efficiency and power density.
I would love to see a robust and repairable class D design make it to the market as a kit or module. It's the one disadvantage I see of class D. Most techs can fault-find on non-switching amplifiers, but blown commercial class D modules typically just end up in the bin.
Hypex (and Purifi) are fairly repairable, and also sound amazing
