McIntosh MC2.1KW Monoblock Amplifier

The McIntosh MC2.1KW is the current flagship monoblock power amplifier — 2,000 watts per channel in a groundbreaking tri-chassis design. Two identical Power Modules feed a single Output Module, allowing McIntosh to deliver unprecedented power reserves while maintaining the pinpoint control and effortless character that defines the McIntosh sound. It sits at the summit of McIntosh’s current amplification range, above the MC1.25KW (1,250W) statement monoblock and the MC611 (600W) reference-tier monoblock.

The tri-chassis architecture is one of the most sophisticated in high-end audio. Each Power Module contains its own dedicated massive power supply, and the two feed into a single Output Module that houses the Quad Balanced output topology and McIntosh’s celebrated Autoformer transformer. The Autoformer ensures that all 2,000 watts are delivered to any speaker load — whether 4, 8, or 2 ohms — without the power droop that afflicts conventional solid-state amplifiers into difficult impedance dips.

Dual sets of balanced XLR and unbalanced RCA inputs allow flexible system integration and bi-wiring configurations. Multiple speaker terminals support bi- and tri-wiring for complex loudspeaker systems. Power Guard prevents clipping. Sentry Monitor protects output transistors. Monogrammed Heatsinks dissipate the heat two thousand watts of amplification produces, and Solid Cinch speaker binding posts deliver McIntosh’s signature mechanical connection quality.

The MC2.1KW is the reference power amplifier for driving the most demanding loudspeakers — the electrostatic panels, planar magnetics, and large multi-way tower systems that lesser amplifiers cannot control. Pairs naturally with the C12000 preamplifier for a top-of-range McIntosh stereo system. At $110,000 the pair in current McIntosh pricing, the MC2.1KW is available for audition at the Scottsdale showroom — walk in during business hours or book ahead for a prepared listening session.
