Before (or perhaps even in spite of) the outstanding solid-state designs of the late 1990s, many ardent McIntosh supporters consider the C22 to be the brand's best preamplifier. It would be challenging to think of one with a more practical selection of settings, features, and functions. There are controls for bass, treble, balance, volume, and even a loudness circuit. There are two tape inputs with full monitoring and seven high-level inputs in total. One set of phono inputs is for moving-coil, the other is for moving-magnet, and the front panel gives users an option between capacitance and loading for mcs and mms. A mode knob allows you to switch between stereo, mono, stereo reverse, left and right to both channels, and mono to both channels.
