The new McIntosh MC2301 mono-block tube amplifier hails the fusion of our Unity Coupled and Quad-Differential circuit topologies. From the inception of McIntosh Labs, Unity Coupling stands as one of the premiere tube topologies ever conceived, making revolutionary power bandwidth and low distortion possible. Quad-Differential circuitry, a recent McIntosh innovation, cancels nearly all inherent noise and circuit-born non-linearities 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 demanding loudspeakers. From classical to full-on rock and roll, the MC2301 delivers the most extraordinarily lifelike and dynamic performance ever heard from a McIntosh tube amplifier.

The MC2301 design is fully balanced from input to speaker output and is the first ever McIntosh tube amplifier to include Quad-Differential circuitry. A blend of tube and solid state devices comprise a super-linear input stage and the output stage, based upon eight KT88 power tubes, terminates in a custom multifilar wound output transformer providing very low distortion and wide power bandwidth. The result? A staggering 117dB signal to noise ratio combined with vanishingly low distortion to provide remarkable low-level linearity and unmatched liquidity.
