There are enough inputs and outputs on the MA9000 to last a lifetime. The 10 analog connections are comprised of 2 balanced and 6 unbalanced inputs plus 1 Moving Coil and 1 Moving Magnet for turntable connectivity. Both phono inputs feature adjustable loading for fine tuning of vinyl playback. All unbalanced analog connectors are made from premium gold-plated solid brass for superior signal handling and grounding. On the digital side, 2 coax, 2 optical, 1 USB and 1 MCT input (for use with our MCT450 SACD/CD Transport) are all housed in our new DA1 Digital Audio Module; the DA1 can be easily replaced by future modules to keep your MA9000 up to date as new digital audio formats and technologies are developed. The DA1 utilizes a powerful 8-channel, 32-bit Digital-to-Analog Converter (DAC) used in Quad Balanced mode. 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. All inputs can be given custom names for user-friendly system control and configuration. All inputs also function independently of each other and each is always available for use regardless of how your sources are connected.
