Bring all your music to life with the MA8900 Integrated Amplifier. It offers 200 Watts per channel and combines many new features with McIntosh's legendary amplification prowess and preamplifier capabilities into one all-encompassing unit.

The MA8900 is the first product to feature the new McIntosh Monogrammed Heatsinks™. They are made from high quality materials with excellent thermal conductivity properties and are so efficient at dissipating heat that they warrant bearing the McIntosh “Mc” logo. Besides helping your MA8900 run cool, they’ll also help it look cool thanks to their new finishing process that results in a higher quality appearance. They are connected to advanced high current output transistors that eliminate thermal equilibrium lag time (or warm-up time) so that the first musical note played sounds just as good as songs played later in your listening session.

To keep up with the ever-changing world of digital audio, all the digital inputs are housed in their new DA1 Digital Audio Module. The DA1 Digital Audio Module can be replaced by future modules to easily keep your MA8900 current with all the latest digital audio formats and technologies. The DA1 comes with an upgraded 8-channel, 32-bit Digital-to-Analog Converter (DAC) used in Quad Balanced mode; it has 6 digital inputs consisting of 2 coax, 2 optical, 1 USB and 1 MCT for use with our MCT450 SACD/CD Transport. The coax and optical inputs will decode music up to 24-bit/192kHz for high resolution audio playback; the USB input accepts even higher PCM signals up to 32-bit/384kHz and supports up to DSD256 and DXD 384kHz. Analog stereo inputs include 1 balanced and 6 unbalanced plus 1 each of Moving Coil and Moving Magnet for turntable connectivity. All inputs can be given custom names for user-friendly system control and configuration. Unlike their previous integrated amplifiers, every input now functions independently of each other and all are always available for use regardless of how you connect your sources.

Besides new Heatsinks and advanced digital audio capabilities, the MA8900 includes many other updates. McIntosh engineers have used new, more powerful control microprocessors to improve overall system operation. They have also incorporated some of the latest audio-grade circuit components to allow the MA8900 to deliver the best sound possible. ​​​​​​​​​​

At 200 Watts per channel, the MA8900 has enough power to properly drive virtually all loudspeakers. And the renowned McIntosh Autoformer guarantees your speakers will always receive the full 200 Watts regardless if they have 2, 4 or 8 Ohm impedance. Other McIntosh features included in the MA8900 are:

  • Power Guard® that monitors and adjusts the sound wave at the speed of light to prevent harsh sounding distortion and clipping that could damage your speakers.
  • Sentry Monitor™ is McIntosh's fuse-less short-circuit protection circuit that disengages the output stage before current exceeds safe operating levels and then resets automatically when operating conditions return to normal.
  • Home Theater PassThru that allows for seamless integration into a home theater system.
  • High Drive headphone amplifier with Headphone Crossfeed Director (HXD®) which can bring an added dimension to headphone listening.
  • A discrete, five-band tone control that permits manual analog adjustment of your favorite recordings.
  • Power Control to send power on/off signals to connected McIntosh components for easy system power up and shutdown.
  • Gold-plated speaker binding posts that prevent corrosion to ensure a quality signal is sent over your speaker cables​ to your speakers.

The entire unit is wrapped in the timeless McIntosh aesthetic with blue watt meters, a black glass front panel, control knobs, illuminated logo, aluminum end caps and a beautiful polished stainless steel chassis.
