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 gives you the best of all worlds with 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.
