With the also new C12000, the developers from Binghamton realized tube and transistor preamplification with complete separation of the control and power sections. In each of the two chassis – the C12000C controller and C12000ST preamplifier – the left and right channels are electrically and mechanically separated to allow true dual-mono operation. The C12000 preamplifier offers 12 analog inputs: six balanced, four unbalanced, and two unbalanced phono inputs, which can now be freely configured as either moving coil or moving magnet inputs with adjustable capacitance, resistance, and gain.

The two-part high-tech preamp offers both a tube and a transistor output. A total of six tubes power the high-level preamp section, with two 12AT7 and one 12AX7A tubes assigned to the left and right channels respectively. The transistor output worka via a discrete, balanced operational amplifier. The phono stage uses four 12AX7A tubes, with two per channel in a fully balanced configuration with RIAA equalization. The new preamp flagship is equipped with four outputs: 1x tube (balanced), 1x transistor (balanced), 1x fixed (unbalanced) and 1x programmable (unbalanced, tube or transistor selectable). For headphones, a high drive amplifier is available, which aims to harmonize with a wide range of models. Finally, the power control functionality allows other connected McIntosh components to be switched on and off automatically.
