C2800 2-Channel Preamplifier

Ideal for 2-Channel Audio Systems

The C2800 Vacuum Tube Preamplifier is a masterpiece of audio passion and engineering precision. Crafted for discerning audiophiles and music enthusiasts alike, performance has been woven into the very fabric of this audio treasure. The C2800 has proudly earned the McIntosh name.

At the heart of the C2800 lies methodically designed vacuum tube circuitry. Leveraging the latest designs to all but eliminate noise and distortion, the C2800 reduces them to minuscule levels. Its four vacuum tubes, or valves, deliver a listening experience that transcends expectations.

INPUTS IN ABUNDANCE

With its 9 analog and 7 digital inputs (16 total inputs), 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). Both phono inputs feature adjustable Gain in 6dB steps from 40dB to 64dB as well as RIAA equalization.

“The C2800 offers a rich and detailed sound signature. The design combines the warmth of vacuum tube amplification and solid-state technology for a dynamic listening experience allowing a clear separation of instruments, vocals, and great imaging… These qualities in my opinion make the McIntosh C2800 a standout choice for anyone who is looking to enhance their audio system.” – The Absolute Sound (watch full video review below)
