C12000 2-Channel Solid State and Vacuum Tube

The McIntosh C12000 is a dual-chain high-end preamplifier that combines both tube and solid-state technology in a modular system. It consists of two separate enclosures: the C12000 Controller (C12000C) for control and power, and the C12000 Preamplifier Module (C12000ST) for audio processing. This separation minimizes interference and enables a true dual-mono configuration for optimal channel separation and sonic purity.
