Class D Monos
The sound is clear and open. The amps have a very tight grip on my loudspeakers. The bass is deep and controlled. The presence region is very detailed and the highs are not sharp or edgy. Ten years ago I tried Class D and was disappointed, but Class D has come a long way. These are very good amps indeed.
