The new McIntosh MC2301 monoblock tube amplifier hails the fusion of our Unity Coupled and Quad-Differential circuit topologies. The Mcintosh Unity Coupled Circuit stands as one of the premiere tube topologies ever conceived, making possible revolutionary power bandwidth and low distortion. Quad-Differential circuitry, a recent McIntosh innovation, cancels nearly all induced noise and circuit-borne nonlinearities resulting in the lowest noise levels ever achieved in a tube amplifier. With 300 Watts available at 8, 4 or 2 ohms, the MC2301 provides power enough to drive even the most difficult loudspeakers. From the demands of massed chorale to full-on rock and roll, the MC2301 delivers the most extraordinarily lifelike and dynamic performance ever heard from a McIntosh tube amplifier.
