Product Description

Strength and Musicality characterise this Tube Amplifier.

Its over engineered Class AB circuit easily provides 2 x 38 watts to the high end gold plated terminals, giving huge freedom to the listener in the selection of a loudspeaker.

On sources side there is also huge flexibility: vinyl lovers can use a separate phonostage or order the Cayin CS-55A with the optional high end MM phono card pre-installed (available for an extra £250.00)

The CS-55A comprises of a fully anodized aluminum front, a vented chassis with a gorgeous finish, the finest hand-made point-to-point wiring, and a soft-start circuit to enhance the life of the toroidal power transformer and output transformers. Combined with audio grade capacitors, carbon film resistors, and ceramic tube sockets, this is one amplifier every audiophile should have in his/her collection. Speaker output impedance can be swapped between 4 ohms and 8 ohms. 

Want to use your computer as a source ? Then the CS-55A comes as standard with a USB 2.0 that can play Hi-Res audio with up to 32bit / 384kHz.

This combination of high-end DAC and classic tube charm is a sublime combination.

The output stage can be switched between the triode and Ultra-linear operation.

On top of that there is an external bias adjustment with meter.

A state of the art headphone amplifier is also included to allow very high performance for even the most difficult to drive headphones.

Selected hand picked components such as the encapsulated Alps potentiometer and ceramic tube sockets round off the quality oozing from this amplifier.
