I'm hesitant to respond because I've never listened to D-Sonic amps. I owned the Peachtree 220SE and their Grand Integrated, both of them are Class D amps. It's my understanding that D-Sonics amps sound much better than Peachtree, but based on my experience I don't think I will own Class D amplifiers again. I currently own a Parasound A-21 and in the context of my system find the sound to be more musical. The Peachtree amps never had a natural sound to them.
