Other characteristics
The CSA100 integrated amplifier is Copland's latest work, which once again combines the advantages of using valves and transistors, resuming the concept of syneptic design that had already made Copland's hybrid amplifiers famous in the past. The CSA100 amplifier employs a 2 x 100W into 8 ohm transistor power final stage, current feedback and powered by a double triode tube preamplifier. A single valve is responsible for the line amplification of the CSA100, demonstrating astonishing efficiency. The double triode tube operates at high voltage in a setup optimized for maximum linearity, taking care of only voltage amplification. A MOS-FET circuit provides the “brute force” capable of driving the line stage output and feedback loop, ensuring maximum cooperation between the world of voltage governed valves and transistor technology, controlled in current. In this integrated, the warm and colorful charm of the old tube project is reborn. In the line stage, the tube provides the sound with life, spaciousness and dynamics difficult to find in amplifiers that rely only on solid-stage technology. For vinyl enthusiasts, the CSA100 has RIAA input for MM cartridges. And for the digital enthusiast, an excellent D/A converter is included with multiple S/PDIF inputs, 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.
