MA12000 Integrated Amplifier
2-channel integrated amplifier with a hybrid design: vacuum tube preamp and solid state power amp
The fully loaded, hybrid MA12000 Integrated Amplifier is a product of uncompromising audio engineering and expert craftsmanship. McIntosh’s most powerful integrated amplifier ever, the feature rich MA12000 offers 350 Watts per channel of clean, high performance power that produces a breath-taking home audio experience. You will think your favourite 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 analogue 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 analogue 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 analogue 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.
For digital music, the MA12000 comes with the DA2 Digital Audio Module factory installed. Located in the DA2 are 7 digital audio inputs: 2 coaxial, 2 optical, 1 USB and 1 MCT (for use with MCT series of SACD/CD Transports), and 1 audio-only HDMI Audio Return Channel (ARC)1 connection. The DA2 is powered by a next generation, Quad Balanced, 8-channel, 32-bit Digital-to-Analogue Converter (DAC). This audiophile-grade DAC features improved dynamic range and improved total harmonic distortion. The DA2 supports high resolution digital audio playback, as the USB input supports native playback of up to DSD512 and DXD up to 384kHz, while the coax and optical inputs can decode digital music up to 24-bit/192kHz.
The DA2 has received Roon Tested designation from Roon Labs, which can be especially useful if you have an extensive library of digital music. It has been profiled and tested by both Roon and McIntosh for maximum compatibility. Roon will recognise it and send it audio optimized for its capabilities. No fiddling with checkboxes or dropdowns, Roon Tested devices are automatically identified and configured out of the box for a superior customer experience.
We have this amplifier available for demonstration in our KJ West One store in Central London.
