McIntosh MA9000 Integrated Amplifier

Model: MA9000 UPC: 842548105850 Item: 169240

Product Information

The second of McIntosh's next generation line of integrated amplifiers, the MA9000 is their biggest integrated at 300W per channel. It combines McIntosh's amplifier and preamplifier expertise into one comprehensive unit.

McIntosh Monogrammed Heatsinks

McIntosh's Monogrammed Heatsinks are made from high-quality materials with excellent thermal conductivity properties. They're so efficient at dissipating heat that they warrant bearing the McIntosh "Mc" logo. A new finishing process is used, which results in a higher quality appearance, and the heatsinks are connected to advanced high current output transistors to eliminate thermal equilibrium lag time.

DA1 Digital Audio Module

All the digital outputs are housed in the new DA1 Digital Audio Module. The DA1 can be replaced by future modules to easily keep the MA9000 current with all the latest digital audio formats and technologies. The DA1 comes with an upgraded 8-channel, 32-bit DAC used in Quad Balanced mode and has 6 digital inputs. The USB input accepts signals up to 32-bit/384kHz and supports up to DSD256 and DXD 384kHz.
