Classé Audio CAV-75

Bridgeable Six Channel Power Amplifier

In really nice condition! Sorry original manual, box, and packing is not available, but we will pack carefully.

This unit has been completely gone over and refurbished in April 2020. (some of the pix are from 'the bench'). This unit is built like a tank.

The CAV-75 offers complete flexibility for use in a wide range of home theatre applications. The six channels of the CAV-75 can be easily customized to meet the amplification needs of the most demanding home theatre systems. You may bridge them to change the configuration to 5, 4, or 3 channels, increasing the power delivered to 1, 2 or 3 speakers to satisfy your theatre demands.

All Classé amplifiers share a common, unique design. Each model employs a massive, shielded toroidal transformer to power our sophisticated, high speed circuitry. In most high-end amplifiers, this power is sent to a small number of large reservoir capacitors for distribution. However, large capacitors are often slow in responding to the rapidly fluctuating energy demands of music and movie effects. The ingenious Classé solution uses a large number of small capacitors distributed throughout each amplifier which are located in close proximity to the circuits they supply. The result is a lightening-quick response, creating fabulous dynamics coupled with a more natural sound!

Microphonics, caused by component vibration and magnetic interference from the passage of electric current through them, has plagued audio designers since the beginning of recorded sound. Isolation is the key. At Classé, we begin with a unique front-end circuit topology that mechanically decouples vibration sensitive components from all sources of vibration. In addition, our transformers rest on a specially designed plate to draw magnetic fields away from the circuitry.

Bl-POLAR? MOSFET? J-FET? Most high-end amplifiers use only one type of transistor. At Classé, we use all three in a unique sequence that makes the most of their particular voltage and input impedance characteristics. In addition, we have designed small but highly efficient extruded aluminum heat sinks that disperse transistor generated heat, ensuring maximum output without distortion.
