About the MC402

The McIntosh MC402 is a legendary 2-channel solid-state power amplifier manufactured from 2002 to 2011 that represents the pinnacle of McIntosh's amplifier engineering. It features an extraordinary quad-differential design consisting of four complete amplifier circuits per channel, whose outputs are combined through McIntosh's exclusive handcrafted Output Autoformer to deliver totally balanced operation from input to speaker output with virtually complete cancellation of noise and distortion. The amplifier is capable of driving any speaker load from 2 to 8 ohms in stereo or 1 to 4 ohms in mono without stress, maintaining full power output regardless of impedance mismatch. The MC402 incorporates McIntosh's patented Power Guard clipping prevention circuit, Sentry Monitor current protection, thermal sensors, DC failure protection, and soft-start inrush protection. Its distinctive 3D glass front panel features illuminated peak-responding wattmeters that display true output power accounting for both voltage and current. The amplifier was awarded The Absolute Sound Editor's Choice Award in 2005 and remains highly sought after in the used market for its sonic transparency and musical accuracy.
