CA-5300 5 Channel Power Amplifier

  • 300 watts per channel
  • Elite Audio Performance
  • Single board, direct signal path
  • Intelligent heat management

The CA-5300 from Classé represents innovation, technological achievement, consummate craftsmanship, and iconic design. Classé amplifiers can consistently deliver top performance and reliability in every installation.

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 miniaturized driver stage is virtually noise free, so every nuance of the original signal reaches the output stage. Vast quantities of clean power are controlled with absolute precision and the finest speakers sound even better.

Heat management in Classé’s Delta series amplifiers is provided by the ICTunnel™ (pronounced Icy Tunnel), a sensor and microprocessor-controlled design 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 amplifier warms up fast and reaches it's ideal temperature in less than fifteen minutes. It remains in it's ideal temperature no matter how hard it is driven.
