About the CS-845A

The Cayin CS-845A Tube Integrated Amplifier is a premium stereo amplifier that delivers 24 watts of power per channel through its advanced Single Ended design operating in Pure Class A mode. This amplifier features a combination of high-quality tube components, including WE6SN7 voltage amplification stage, 300B driver tubes, and powerful 845 output tubes, ensuring superior audio reproduction and sound quality. On the rear panel, it provides three pairs of line inputs, a Pre-In connection for external preamplifiers, and speaker terminals suitable for 4 and 8 ohm speakers. The amplifier is equipped with user bias controls for easy adjustment of the 845 tubes, along with a bias meter for monitoring on the top plate. Additionally, the hum balance adjustment specifically for the 300B tube allows for precise control of the hum level. The CS-845A also features a front-mounted Negative Feedback (NFB) switch that offers two levels for customizable sound output. At 0dB NFB, the amplifier creates an open and detailed sound profile, while the -3dB setting delivers a softer, cleaner audio experience. It showcases an anodized aluminum front panel and a fully vented chassis, meticulously crafted with hand-made point-to-point wiring and high-end components such as an Alps volume control, audio-grade capacitors, carbon film resistors, and a toroid transformer for power supply. The wide bandwidth EI output transformer and ceramic tube sockets guarantee optimal performance. Conveniently, the CS-845A comes with a remote volume control and retains the last setting when powered off. It is available in two elegant front finishes: Silver and Black.
