This Audio Research D60 Amplifier with the black brushed aluminum faceplate is in perfect working order and in excellent physical condition. Just like all AR amps this solid amp is built like a tank, using only the highest quality functional components of near military construction.
Tested and detailed on our bench the amp performed as it should. We later hooked it up to one of our systems for a few days and it worked flawlessly.
