CP-700

About the CP-700

The Classé CP-700 is a sophisticated preamplifier from the Classé Delta series, designed with cutting-edge balanced circuit topologies to optimize noise reduction and dynamic performance. It features a fully balanced design with a signal-to-noise ratio of 100dB over a frequency range of 20Hz to 500kHz. The power supply is housed in a separate chassis to enhance isolation and reduce interference, utilizing one transformer with five separate secondary windings for audio and control circuits, and another transformer dedicated to sensor and protection circuits. The total harmonic distortion plus noise is impressively low at 0.0012%. The CP-700 employs a unique double cross-balanced approach in its gain stages, with six signal paths per channel including inverting, non-inverting balanced circuits, and a single-ended circuit. This design contributes to its clean, detailed sound quality. The preamplifier also includes two separate volume controls for each channel and selectable gain settings to accommodate both low-output moving coil (MC) and high-output moving magnet (MM) cartridges, with gains of 72 dB and 42 dB respectively. The unit is designed with high-quality components such as low-noise film resistors and capacitors to ensure superior audio fidelity. Overall, the CP-700 is recognized for its meticulous engineering and excellent sonic performance, making it a top-tier choice for audiophiles seeking a high-end preamplifier.
