McIntosh will be celebrating our 75th Anniversary in 2024. To commemorate this milestone, the first 75 pairs of MC2.1KW sold in 2024 to each country McIntosh is distributed in will include special anniversary badging. The Output Module will have a dual anodized laser-engraved badge proudly displaying our 75th Anniversary logo on the top, while the handles on all three modules will have “75 years” engraved in them. These additions are sure to make every MC2.1KW built through 2024 a true collector’s item for McIntosh enthusiasts.


Thanks to our hand wound Autoformer, the full 2,000 Watts of power can be delivered into a speaker regardless if its impedance is 2, 4 or 8 Ohms. This means you won’t need to sacrifice any power if your speaker impedance doesn’t match the amplifier’s output impedance. That’s because amplifiers from most other brands only have one output impedance and if that doesn’t match your speaker’s impedance, then you could sacrifice up to half of the amplifier’s power capabilities. This will not happen with our Autoformer and its unique ability to output full power at three separate impedances.


The MC2.1KW succeeds the MC2KW, which rocked the Las Vegas convention hall – and the entire audio world – when it was introduced at the 2005 CES Show. The next generation MC2.1KW offers many sonic upgrades. Chief among them are substantially larger filter capacitors that improve the performance of low end frequencies as well as significantly improving dynamic headroom. These eight larger capacitors are located in the Power Modules behind the custom Power Bank that is visible through the front panel glass.


New on the MC2.1KW are dual sets of balanced and unbalanced inputs, conveniently allowing you to connect more than one preamplifier. This gives you the ability to easily switch between vacuum tube and solid state signals, such as from our reference level C12000 Solid State and Vacuum Tube Preamplifier that has outputs for both signal types, or from separate vacuum tube and solid state preamplifiers. Or use the second set of inputs to connect two preamplifiers of the same type, the choice is yours.

MC2.1KW 1-Channel Solid State Amplifier is also part of the Reference Music System

Available separately or as part of our Reference Music System and Reference Home Theater System, the MC2.1KW pairs seamlessly with our XRT2.1K Loudspeaker or its predecessor, the XRT2K. However, its versatility knows no bounds and it’s not limited to just being used with McIntosh speakers but instead can be used with a wide variety of other speakers. It is ideally suited for audio systems that have power hungry loudspeakers; systems located in extremely large rooms; or for audio enthusiasts who simply demand the latest and best in state-of-the-art home audio amplification.
