The MC501, 500 watt mono block amplifier has a new and bold, yet unmistakably McIntosh look. It features 3-dimensional glass and new cool-running, ultra long life, fiber optic LED lighting. The chassis gleams in polished stainless steel. Upward facing connectors at the back make attaching cables easier. The extraordinary quad-differential amplifier design reduces noise and distortion to record low levels. Total Harmonic Distortion: 0.005% maximum from 250 milliwatts to rated power output for 2 channels. Specifications are very conservative.
