The new McIntosh MC2301 monoblock 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 possible revolutionary power bandwidth and low distortion. Quad-Differential circuitry, a recent McIntosh innovation, cancels nearly all inherent noise and circuit-born 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 demanding 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. 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.

EXCLUSIVE MCINTOSH POWER ASSURANCE SYSTEM A collection of technologies that enhance performance and reliability while protecting the amplifier and loudspeakers.

SENTRY MONITOR® TUBE PROTECTION Fuse-less short-circuit protection circuit disengages the output stage before current exceeds safe operating level – resets automatically.

UNITY COUPLED OUTPUT CIRCUIT® Output power is taken from both the plate and cathode of the output tubes. Conventional designs only take output from the latter. This allows ½ the turns ratio, or ¼ the impedance transformation of conventional designs. The result is much lower distortion, wider bandwidth and increased loudspeaker damping factor.

WATTMETER Swift, accurate response reveals program peaks so staying within the power limits of your loudspeakers is easy.
