The CSA150 amplifier is equipped with a 2 x 150 W semiconductor stage with current feedback of the power stage, and the signal is supplied from the preamplifier operating on a double triode.
One tube is responsible for the linear amplification of the CSA150. The applied solution is distinguished by amazing efficiency. The dual triode operates at high voltage in a configuration for maximum linearity, taking care only of the voltage amplification. The MOS-FET circuit, in turn, provides a powerful force that drives the linear stage output and feedback circuit, thus facilitating the collaboration between the world of voltage-controlled electronic tubes and current-controlled transistor technology.
If you want the warm and colorful charm of older tube designs, the CSA150 tube linear stage will give you that experience. In this case, the tube creates life, space and dynamics that are difficult to find in amplifiers based solely on solid state technology.
With the vinyl enthusiast in mind, the designers have equipped the CSA150 with a RIAA-corrected input for MM cartridges. The amplifier also uses an excellent DAC with multiple S / PDIF, PCM and DSD inputs, based on the 32-bit ES9018 Reference chip in a quad-mono configuration, 8 mono to 2 stereo configuration.
