C500P

About the C500P

The McIntosh C500P is a high-end solid-state preamplifier designed as part of the modular C500 system, which separates the control unit (C500C) from the amplification section. It features a luxurious two-box design with the power supply and control section separate from the audio processing chassis to ensure pure audio performance. The C500P employs a dual-mono design with completely separate and shielded circuitry and power supplies for each channel, providing excellent channel isolation and low noise. It includes four balanced high-level inputs, four unbalanced inputs, and dedicated MM and MC phono inputs with selectable loading options. The volume control uses a multi-stage precision digitally controlled attenuator with an optical encoder rotary control, ensuring channel tracking accuracy within 0.1 dB and 213 steps of 0.5 dB increments without noise. The preamplifier supports input level trim adjustment to match volume levels across inputs and features a balance control with 1 dB steps. The front panel has an alphanumeric fluorescent display showing source selection, volume, and balance levels. Technical performance includes a frequency response of 10 Hz to 40 kHz (-0.5 dB), total harmonic distortion of 0.002% max (20 Hz to 20 kHz), signal-to-noise ratio of 100 dB for high level and 88 dB for phono, and output impedance of 220 ohms balanced and unbalanced. The unit measures 44.45 cm wide, 15.24 cm high, and 58.42 cm deep, weighing approximately 11.39 kg net. It is designed for audiophiles seeking uncompromised refinement, precision, and flexibility in a solid-state preamplifier.
