The McIntosh C2700 is the kind of preamplifier that earns every square inch of rack space it occupies — six vacuum tubes glowing through a top glass panel, the iconic backlit black fascia, and those blue output meters doing exactly what they've always done: making every listening session feel like a proper occasion. Sonically it's unmistakably McIntosh: a rich, authoritative midrange where voices feel present and textured, bass that stays controlled and grounded without ever going soft, and a musical ease that keeps hours from feeling like hours. The DA2 module brings an honest high-resolution DAC into the equation — coaxial and optical up to 24-bit/192kHz, USB to DSD512, even HDMI ARC for the TV — not as a concession to modernity, but as a genuinely capable front-end. Both phono inputs (MM and MC, adjustable) are excellent. This is a full-featured reference preamp wearing a heritage badge it actually earned.

Liner Notes
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.
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. 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.
For analog music, the C2700 has 9 inputs comprised of 3 balanced connections, 4 unbalanced connections, along with 1 Moving Coil and 1 Moving Magnet phono inputs for connecting a turntable or two. With a total of 16 inputs, the C2700 has a virtually infinite number of inputs to connect all your music sources. Our dual chassis design keeps the analog and digital sections separate to prevent signal corruption.
