McIntosh MC2.1KW (2024–)
The McIntosh MC2.1KW is the most powerful amplifier the company has ever made. It was introduced as part of the brand's 75th anniversary. Announced in February 2024, it succeeds the MC2KW, which debuted at the 2005 CES show. This is a monoblock - one chassis per channel - and the pricing reflects that. A single amplifier, not a pair, was listed at £66,900 by UK dealer KJ West One. Canadian dealer Audio Excellence Canada listed it from $78,000 CAD. Fidelity Magazine (2024) reported a US retail price of $50,000.
The MC2.1KW is built in three chassis. Each unit has one Output Module and two Power Modules, and each Power Module contains a 1,000-watt amplifier. The power audio circuitry is split across the two Power Modules, which also house the power supplies and McIntosh's monogrammed heatsinks. The third chassis, the Output Module, holds the bi-filar wound Autoformer, the speaker outputs, and dual sets of unbalanced RCA and balanced XLR inputs. The signal from the preamplifier enters the Output Module. The amp delivers 2,000 watts of continuous power into 2, 4, or 8 ohm loads. The Autoformer is what keeps that power consistent regardless of speaker impedance.
The MC2.1KW was offered as a 75th Anniversary Edition, limited to 75 pairs. The Output Module weighs 125 lbs (56.7 kg), and each Power Module weighs 145 lbs (65.8 kg). McIntosh pitched it as a match for the XRT2.1K speaker or its predecessor, the XRT2K. A 3-year warranty was standard. McIntosh's own advertising and dealer copy called it "the ultimate power in home audio amplification" and "the most powerful McIntosh amplifier ever created." With 2,000 watts on tap, those claims are not hard to believe.
