I have zero experience with Class D amps, other than with the new Bash 300s I installed in my sub (and love). However, just recently I read a few articles about the newest Krell Class D amps (the XD series) and they get glowing, stellar reviews - I was actually impressed by what I read (that, in itself, speaks volumes because I’m an old and hardcore analogue guy) and think you should research these before you make a decision.
Good luck!
