Welcome to our website! As we have the ability to list over one million items on our website (our selection changes all of the time), it is not feasible for a company our size to record and playback the descriptions on every item on our website. However, if you have a disability we are here to help you. Please call our disability services phone line at (508) 771-4434 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our website, help conduct advanced searches, help you choose the item you are looking for with the specifications you are seeking, read you the specifications of any item and consult with you about the products themselves. There is no charge for the help of this personal shopper for anyone with a disability.

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 MCT500 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 our 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.

With "a fluid sound" that's "without hardness," the MA8900 can "cope with the most difficult speakers." Unlike many solid state amplifiers, the MA8900 "creates no tiredness" of listening and does so "without sacrificing the speed or sharpness sometimes necessary" for certain types of music while at the same time it can do "justice to the volume of a symphonic orchestra" and exhibit "extreme refinement when the music requires it." Awarded d'Or 2017 Hi-Fi Award - Diapason


Besides new heatsinks and advanced digital audio capabilities, the MA8900 includes many other updates. Our 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.


"The MA8900 doesn't sound good - it sounds marvelous, on all types of music. It engenders a sense of pride of ownership, has Cadillac build quality, [and] intelligent user features." - StereoNET


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 our 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 MA8900 is one of many McIntosh products to receive Roon Tested designation from Roon Labs. It has been profiled and tested by both Roon and McIntosh for maximum compatibility. Roon will recognize 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.


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. Contact your local dealer to learn more.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy, and expensive and you probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.
