The C8 Vacuum Tube Preamplifier has an open chassis industrial design similar to our popular MC275 Vacuum Tube Amplifier, and MA252 and MA352 Integrated Amplifiers. When combined with an amplifier (like the matching MC830 Amplifier), source components such as a turntableCD player (see the matching MCD85 SACD/CD Player) or streaming music player, and a pair of speakers, it can help deliver a lifelike audio experience in your home.

Similarly sized to our MA252 Integrated Amplifier, the C8 is powered by four 12AX7a vacuum tubes housed inside stylish protective cages. For inputs, the C8 comes with 1 balanced and 2 unbalanced analog inputs, plus 1 Moving Coil and 1 Moving Magnet phono inputs with adjustable loading to play cherished vinyl collections. All inputs can be given user-friendly names in order to simplify user control. Bass and treble tone controls help fine tune your music to your personal preferences. For outputs, it has 1 balanced and 2 unbalanced; 1 of the unbalanced outputs can be configured as a subwoofer output for use with a powered subwoofer to further enhance low frequencies.

While the C8 does not come equipped with any digital inputs, it is digital-audio-ready as our DA2 Digital Audio Module can be installed in it. Adding the DA2 is an optional dealer installed upgrade. The DA2 has 7 digital inputs: 2 coax, 2 optical, 1 USB, 1 MCT (for use with our MCT500 or MCT80 SACD/CD Transport), and 1 audio-only HDMI Audio Return Channel (ARC)1 connection. The DA2 is powered by a next generation, Quad Balanced, 8-channel, 32-bit Digital-to-Analog Converter (DAC). Its audiophile-grade DAC is highlighted by improved dynamic range and improved total harmonic distortion. For high resolution audio playback, the USB input can support native playback of up to DSD512 and DXD up to 384kHz, and the coax and optical inputs can decode digital music up to 24-bit/192kHz.
