McIntosh MA12000 2-Channel Integrated Amplifier

The fully loaded, hybrid MA12000 Integrated Amplifier is a product of uncompromising audio engineering and expert craftsmanship. Our most powerful integrated amplifier ever, the feature rich MA12000 offers 350 Watts per channel of clean, high-performance power that produces a breathtaking home audio experience. You will think your favorite musicians are playing a live, in-person performance in your house.

The MA12000 includes our Hybrid Drive^™ technology that uses the best of vacuum tubes and solid state to produce the best sound performance. It gives you the warm nuances of a vacuum tube preamplifier (or valve preamplifier as some of our friends like to say) combined with the speed and raw power of a solid-state amplifier, state-of-the-art digital audio capabilities, and enough analog audio connections for virtually any home music system.

The MA12000 is a hybrid design with the preamplifier section powered by (4) 12AX7A vacuum tubes (2 tubes per audio channel), while the 350 Watt power amplifier section employs a solid state design. Our Autoformer^™ technology guarantees your speakers will always be capable of receiving that full 350 Watts whether they have 2, 4 or 8 Ohm impedance.

There are 10 analog inputs on the MA12000 consisting of 2 balanced and 6 unbalanced inputs, plus 1 Moving Coil and 1 Moving Magnet input for connecting a turntable. Both phono inputs feature adjustable loading for fine tuning the MA12000 to your specific turntable configuration so your vinyl collection sounds just right. All the unbalanced analog connectors are constructed from premium gold-plated solid brass for superior signal handling and grounding. The MA12000 also has 1 balanced and 1 unbalanced output if you ever want to connect to an additional amplifier that’s used in a different part of your residence.
