The C32 is one of the more rare vintage McIntosh pieces, and this example is in pristine condition. There are two totally independent left and right stereo program lines running through the preamplifier, which would allow the user to listen to music, while recording or dubbing a completely separate program, which was a very useful feature prior to digital media. Parlor tricks aside, this preamp is a workhorse, and you can hardly go wrong with a McIntosh.

- Liner Notes
- "The McIntosh C32 preamplifier provides the most comprehensive range of functions and control options. Many of these are new in a preamplifier. The C32 is a dual stereo preamplifier with a built-in monitor power amplifier. There are two totally independent left and right stereo program lines running through the preamplifier. One program line is the listen program line. the other is the record program line. Each program line can select its own program source from any connected input signal i.e. phono, tuner, aux or tapes 1, 2 or 3 without interference with the other program line. The output of the listen program line is affected by all the front panel controls (except the record switch) and is fed to the main output and/or output 1 and 2 jacks as selected by front panel push buttons. The output of the record program line is not affected by front panel controls (except the record switch) and is fed to all output record jacks. The monitor amplifier program may be selected from either the listen or record program lines. Separate gain controls for left and right monitor amplifier are located on the top panel. The signal selected for the monitor amplifier is fed to the front panel headphone jacks and the rear panel output line and monitor output connectors." - HiFiEngine
