C2700

Following in a long line of revered McIntosh vacuum tube preamplifiers is the C2700 Tube Preamplifier. Using our well-established vacuum tube topology, the C2700 also features our advanced DA2 Digital Audio Module technology to combine cutting edge digital music capabilities with time tested vacuum tube performance.

A worthy successor to our popular DA1 Digital Audio Module, the DA2 features an expanded set of capabilities. The DA2 offers 7 digital inputs including all the same connections found on the DA1 (2 coaxial, 2 optical, 1 USB and 1 MCT) plus a new audio-only HDMI Audio Return Channel (ARC)¹ connection. TVs with a compatible HDMI (ARC) output can be connected to the C2700 to enjoy your TV’s sound through your home audio 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 TV remote can control the power and volume of the C2700 when CEC communication is enabled in both the preamplifier and the TV. Besides these new HDMI (ARC) features found in the DA2, its USB input has increased DSD playback support up to DSD512 compared to the DSD256 limit of the DA1.

The DA2 is powered by a next generation, 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 DA1. The coax and optical inputs in the DA2 can decode digital music up to 24-bit/192kHz for playback of high resolution audio. Finally, 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 from your SACDs.
