Bring all your music to life with the MA8900 Integrated Amplifier. The first of McIntosh's next generation line of integrated amplifiers, 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.
OVERVIEW
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 a 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 the 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. It has 6 digital inputs consisting of 2 coax, 2 optical, 1 USB and 1 MCT for use with the MCT450 SACD/CD Transport.
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 McIntosh's 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.
