The C12000 Preamplifier is the next generation of McIntosh's acclaimed two-chassis preamplifier design. The two-chassis design allows the audio section to be completely separated from the control and power sections. The absolute isolation of a preamplifier's two main functions – control and sound – is achieved by this unusual but effective design. Splitting these primary purposes of a preamplifier up into separate chassis will deliver the purest sound reproduction possible.
