Copland CSA100 Amplifier Black

The CSA100 integrated amplifier is Copland's latest work, which combines the advantages of valves and transistors, reviving the concept of synectic design that had already made Copland's hybrid amplifiers famous in the past.

The CSA100 amplifier uses a 2 x 100W into 8 ohm transistor power amplifier, current feedback and fed by a double triode valve preamplifier.

A single valve is responsible for the line amplification of the CSA100, demonstrating surprising efficiency. The double triode valve operates at high voltage in a setup optimised for maximum linearity, taking care of voltage amplification only. A MOS-FET circuit provides the “brute force” to drive the line stage output and the feedback circuit, ensuring maximum collaboration between the world of voltage-controlled tubes and current-controlled transistor technology.

In this integrated, the warm and colorful charm of the old tube design is reborn. In the line stage, the tube gives the sound life, spaciousness and dynamics that are difficult to find in amplifiers that rely only on solid-state technology.

For vinyl enthusiasts, the CSA100 has RIAA input for MM cartridges. And for digital enthusiasts, an excellent D/A converter is included with multiple S/PDIF, PCM, and DSD decoding capabilities via the ES9018 Reference 32-bit DAC in quad-mono configuration, from 8 mono to 2 stereo. There is also a headphone output with dedicated circuitry.
