The MA8950 comes standard with the DA2 Digital Audio Module instead of the DA1 Digital Audio Module that came in the MA8900. The DA2 offers 7 digital inputs: 2 coaxial, 2 optical, 1 USB, 1 MCT, and 1 audio-only HDMI Audio Return Channel (ARC)1 connection. TVs with a compatible HDMI (ARC) output can be connected to the MA8950 to enjoy your TV’s sound like never before through your home music system. Popular multi-channel audio formats from Dolby® and DTS® are supported and will be expertly converted to 2-channel audio for proper playback. The MA8950 remote can control the TV’s power and volume when CEC communication is enabled in both the amplifier and the TV. The DA2 also features increased DSD playback support of up to DSD512 via the USB input.
The DA2 is powered by an audiophile-grade, Quad Balanced, 8-channel, 32-bit Digital-to-Analog Converter (DAC) that has improvements in both dynamic range and total harmonic distortion compared to the DAC in the DA1. The coax and optical inputs in the DA2 can decode digital music up to 24-bit/192kHz for playback of high-resolution audio. The DA2 has a McIntosh exclusive MCT input that offers a secure DSD connection to any of our MCT series of SACD/CD Transports to deliver the best possible sound quality of the high-definition audio found on your SACDs. And with its modular design, it's possible to someday replace the DA2 with a newer Digital Audio Module.

Features
2-Channel Integrated Amplifier
- 200 Watts x 2 channel
- 5-band tone control
