For sale is an excellent condition Mivera Audio 1200AS Icepower Class D Amp in black case. Mike sold these almost exclusively here on AC. This one has balanced input connections, but you can find balanced to RCA cables at Monoprice and other places, so it can easily connect to your preamp. This amplifier is dead quiet, produces about 600 watts/channel and can be left on all the time and never gets more than warm. There is a touch-sensitive on/off switch on the bottom right front, but I just left the amp on all the time as Mike suggested.
