The C53 might be the last preamp you’ll ever need for all McIntosh audio enjoyment in your San Diego home. Aside from its 9 analog inputs, this solid-state preamp features the new DA2 Digital Audio Module with 7 digital inputs, including HDMI ARC for TV audio. This module is upgradeable, so the C53 can accommodate the next generation in digital audio. The analog circuitry, 8-band equalizer, and classic McIntosh styling? That will never need updating.
