Cayin | CS-845M | Pair | High-End Vacuum Tube Mono Power Amplifier.

Single-Ended Tube Power Amplifier. Mono power amplifier output power of 2x 28-watt Class-A.

in design to the cayin CS-6LA preamplifier. Their 300B tubes in the driver stage, in conjunction with the 845 end tubes, mobilize a high single-ended output power of 28-watt Class-A per channel. Each mono block uses a TUNG-SOL 6SL7 and 6SN7GTB tube as a voltage amplifier. The Russian TUNG-SOL tubes used are perfect for high-quality audio applications. The tube amps sound delicate and warm without distorting the sound.

Externally accessible controls and the display via the integrated measuring instrument allow the user to easily adjust the optimal operating point of the 845 tubes.

For use in the CS-845M top mono blocks, Cayin developed two different transformers: a toroidal transformer that has a high inductance and allows high efficiency in the power supply with low resistance. In the EI transformer of the output transformer, a special, multi-layer winding process is used to achieve particularly balanced and realistic sound.

The high standards of the Cayin CS-845M mono blocks are also reflected externally. Their high-quality aluminium panels impress with their strong oxidation resistance and low surface light sensitivity. The process of manual housing painting is time-consuming, but this creates a mirror-smooth and fine surface with uniform color and gloss.
