C1000 Preamplifiers

The C1000 stereo preamplifier utilizes a multi-chassis design where the control and power section is isolated from the pure audio sections. This lavishly engineered, unorthodox approach accomplishes absolute isolation of the two main preamp functions: control and sound. ​

The C1000 consists of three separate modules: a C1000C control unit, a C1000P transistor preamplifier, and a C1000T vacuum tube preamplifier. Inside each module, the left and right channels are electrically and mechanically isolated from each other to allow true dual mono operation - resulting in the ultimate stereo separation and sonic purity.

You can choose to have your system configured with either the transistor preamplifier for the absolute finest crystalline sound quality, or with the tube preamplifier to produce that warm, organic tube sound. The C1000C control unit can also be configured with both the transistor and tube preamp sections simultaneously, allowing you the luxury of choice.

For ultimate stereo fidelity, the preamplifier modules employ dual mono topologies yielding over 130dB of channel separation. The C1000 preamplifier utilizes fully balanced circuitry to compliment the level of performance achieved in any of McIntosh’s power amplifiers that utilize Quad Balanced Circuitry.
