McIntosh MC303

At 300 watts per channel the new McIntosh MC303 Three Channel Power Amplifier with Autoformers delivers its maximum rated output power into 2, 4, or 8 ohm loads for the lowest noise and distortion performance possible. Premium cosmetics featuring a Â½” thick glass faceplate, custom machined and anodized aluminum handles, and a mirror polished stainless steel chassis are standard equipment on the MC303. Power Guard, a McIntosh circuit innovation, maximizes sound quality at high power levels while our Sentry Monitor feature provides continuous short circuit protection of the amplifier and connected loudspeakers. A triple bank of Peak Reading Watt Meters provides instant recognition of power output and may be switched off for theater use.$14,990 rrp
