  • Own a piece of a legend in audio—McIntosh. This monoblock tube amplifier is a fusion of McIntosh’s Unity Coupled and Quad-Differential circuit topologies. Together they deliver the most extraordinary, lifelike and dynamic performances ever from a McIntosh tube amp. The Unity Coupled design makes provides revolutionary power bandwidth with low distortion, while the Quad-Differential circuitry (a McIntosh innovation) cancels nearly all induced noise and circuit-borne nonlinearities. The result—the lowest noise levels McIntosh has ever achieved in a tube amplifier. Provides 300 watts available at 8, 4 or 2 ohms to a single channel—enough power to drive even the most sophisticated loudspeaker.
