I would like to share my experience/impression with class D amps. I started with a Virtue Audio Sensation. It was good but when I switched to Bel Canto S300i it was an amazing improvement in every aspect. Just over a week ago I switched to ClassDAudio SDS-470C with upgraded power supply. The improvement from Bel Canto is amazing. Now I feel it is closer to good ClassAB amps. For the remainder of my system I have a Squeezebox touch and Monitor Audio Silver 2 speakers.
