C2800

Vacuum Tube Preamplifier

The C2800 Vacuum Tube Preamplifier is a masterpiece of audio passion and engineering precision. Crafted for discerning music lovers, performance has been woven into the very fabric of this audio treasure.

At the very heart of the C2800, lies methodically designed vacuum tube circuitry.

With a staggering 16 inputs (9 analog, 7 digital), the C2800 will become the nucleus of your home audio system.

There are 3 balanced and 4 unbalanced analog inputs, plus 2 phono inputs that can be configured for either Moving Coil or Moving Magnet phono cartridges to connect your turntable(s).

DA2 Digital Audio Module houses 7 digital inputs and is powered by an audiophile-grade Quad Balanced, 8-channel, 32-bit Digital-to-Analog Converter (DAC).

The DA2 offers an array of connections, including an audio-only HDMI Audio Return Channel (ARC) input, ushering your TV sound into a new era through your home stereo system.

The DA2's other 6 digital inputs consist of 2 coaxial, 2 optical, 1 USB, and 1 MCT. The USB input supports DSD512 and DXD 384kHz. The coax and optical inputs decode digital music up to 24-bit / 192 kHz for high resolution audio playback.

3 stereo sets of variable balanced and unbalanced outputs to connect the C2800 to your power amplifier(s).

Features the return of the Processor Loop, something that was not available on the last few generations of McIntosh preamplifiers.

Connect to your network to unlock control options offered through our complimentary Connect app.

With the C2800, experience the warmth and richness that only vacuum tubes can offer, elevating your listening experience to new heights.
