How is it? Great, for the price. Overall I’d say it’s a #classD #amp that doesn’t have the weaknesses most class D amps. It sounds better than the $300 tier Yamaha amps but not better than their true audiophile class stuff. Highlights for me are the very natural sounding bass, and it’s very detailed and articulate. I won’t be giving up tubes anytime soon for this, but the #AiyimaA07 is crazy nice and I’m looking forward to using it with my #KefQ150 in the office because it should synergize well.
