One Classé Audio CA-5300 Five Channel Power Amplifiers in a very good condition. A ground-breaking performance, prodigious power, sophisticated control and rock-steady reliability. Classé’s new Delta series is a giant leap in amplifier design thanks to exclusive ICTunnel and audio technologies. The Classé design team has created the ultimate environment to amplify an audio signal. The entire amplification process occurs on a single board, creating the most direct and transparent signal path conceivable. The uniquely miniaturized driver stage is virtually noise free, so every nuance of the original signal reaches the output stage. Here, vast quantities of clean power are controlled with absolute precision. Suddenly, the world’s finest speakers sound even better. Heat management in Classé’s new Delta series amplifiers is provided by the ICTunnel, a sensor- and microprocessor-controlled technology inspired by the heatsinks found in high-power laser and medical equipment. Mounted inside the unit, the ICTunnel actively regulates the amplifier temperature to ensure both optimum performance and reliability. From room temperature, the amplifiers warm up fast. They reach their ideal temperature in less than fifteen minutes and remain there regardless of how hard they are driven. No conventional heatsink can do this. The original boxes included.
