NEW McIntosh MA12000 Hybrid Integrated Amplifier (Retail $15,000)

McIntosh MA12000 new in the box! 

I purchased a system a few months ago and one of the meters on the MA12000 would stick from time-to-time. McIntosh promptly sent me a brand-new unit and before I opened it, I decided to make a major change in the system and no longer needed the unit. Incredible opportunity for someone looking for this piece, as it’s extremely difficult to find one below the $15,000 MSRP. NOTE: McIntosh warranties are limited to the original owner, please assume the warranty is NON-transferable.

PHOTOS: Stock photos have been provided as the new MA12000 has not been removed from the box. The photo of the entire system includes the original unit, prior to replacement. The other components shown are also for sale, including the: MT5 turntable, the MPC1500 power controller, and the LB200 light box, as well as the (not pictured) Monitor Audio Platinum 300 3G speakers in piano ebony finish (the orange and black tiger striped look). The MA12000 is also for sale at the original dealer's shop in Corona Del Mar, CA, and available for local inspection and/or pickup.

From McIntosh: 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.

For digital music, the MA12000 comes with our 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 our 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-Analog 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 HDMI (ARC) input allows TVs with a compatible HDMI (ARC) output to be connected to the MA12000 and your home stereo system to bring a new level of audio performance to your TV and movie watching that TV speakers or soundbars just can't provide. Popular multi-channel audio formats from Dolby® and DTS® are supported and will be expertly converted to 2-channel audio for proper playback.
When CEC communication is enabled in both the MA12000 and your TV, your TV remote can control the power and volume of the MA12000. The DA2 can be replaced by future modules to keep your MA12000 up to date as new digital audio formats and technologies are developed.

The top of the MA12000 is highlighted by some updated industrial design elements. The Autoformers and power transformer are now contained in a new glass topped enclosure capped by a glass name plate encircled with a decorative trim ring. Key performance specifications and a detailed block diagram are printed on 5 glass panels.

Other MA12000 features include:
•    Power Guard® that monitors the output signal for over driving and makes real time micro adjustments to the input signal to prevent harsh sounding clipping that could potentially damage your speakers
•    Our fuse-less short-circuit protection circuit Sentry Monitor™ that disengages the output stage before current exceeds safe operating levels and then resets automatically when operating conditions return to normal
•    A pair of peak responding, trademarked "McIntosh Blue" Watt meters that indicate the real time power output of each audio channel
•    McIntosh Monogrammed Heatsinks™ which are connected to advanced high current output transistors that minimize thermal equilibrium lag (or warm-up) time and help keep the MA12000 running cool
•    Home Theater PassThru that allows for seamless integration into a home theater system
•    Our patented Solid Cinch™ speaker binding posts that easily but securely attach the speaker cables to prevent them from coming loose and possibly causing a short; the binding posts are also gold-plated to prevent corrosion and ensure a quality signal is sent over your speaker cables to your speakers
•    A discrete, eight-band tone control that allows for advanced manual analog adjustment of your favorite recordings
•    High Drive headphone amplifier with Headphone Crossfeed Director (HXD®) which can bring an added dimension to headphone listening
•    Power Control to send power on/off signals to connected McIntosh components for easy system power up and shutdown
•    Doubling of filter capacity compared to our other integrated amplifiers for even better low frequency performance
•    The latest audio-grade circuit components to deliver the best sound possible
•    Powerful control microprocessors to improve overall system operation
•    Easy operation via front panel controls or the included comprehensive remote control
