Frequently Bought Together
Product Overview & Specifications
Setting a new musical standard in Single Ended 845 monoblocks
With 300B tubes in the driver stage, and in conjunction with the 845 power valves, these Monoblocks from Cayin drive with a high single-ended output of 28 watt (Class A) per channel.
Each mono block uses hand-matched TUNG-SOL 6SL7 and 6SN7GTB tubes which after lengthy testing proved to be the absolute best musically.
These tube Monoblock Amplifiers sound beautifully organic without falsifying the sound, but have immense drive and control, so effortless dynamic realism is brought to the fore.
Externally accessible controls and display via the integrated meter allow the user to easily adjust the optimum operating bias point of the 845 tubes, and therefore tube rolling is an absolute breeze!
Cayin developed two different transformers for use in the CS-845M Monoblocks: a toroidal transformer, which has a high inductance and low resistance allowing for incredibly high efficiency in the power supply.
The EI transformer of the output transformer uses a special, multi-layer winding process to achieve particularly balanced and realistic sound - this design has proved to be the heart and soul of the Cayin sound.
