 Cayin CS-845A Integrated Tube Amplifier 


Introducing the Cayin CS-845A Integrated Amplifier, a single-ended Class-A amplifier that redefines the potential of the 845 valve. Meticulously designed and point-to-point hand-wired with heavy gauge silver-plated signal cables, the CS-845A elevates tube amp reproduction quality to new heights.


This amplifier features an over-engineered toroidal transformer with a soft start switch-on delay, providing a robust power supply. Hand-picked and matched tubes, including high-quality 300B driver tubes with porcelain bases, ensure homogeneous music playback with the highest resolution.


For personalized sound tuning, the CS-845A offers adjustable negative feedback between 0 dB and -3 dB, allowing for precise control and tonal character adjustment to match your speakers. Easily accessible potentiometers on the top panel facilitate quick adjustments, and the integrated Bias Meter provides feedback for bias settings.


All functions, including negative feedback adjustment, can be controlled via the remote. The CS-845A features a high-quality Japanese ALPS volume control and a preamp input for use as a pure power amplifier. Delivering 24 watts of pure Class A power, it connects to speakers via gold-plated terminals.


The Cayin CS-845A is a sophisticated amplifier designed for audiophiles seeking unparalleled sound quality and control.
