The tube amplifier integrated CS-55A represents the most recent advancement in the technology of high end valve based amplification made by Cayin. This machine is state of the art is capable of delivering, with 4 power tubes KT-88 that are configured in push-pull, 40 watts per channel in Class AB mode and ultra-linear.

The CS-55A is equipped with 4 source inputs: an input for Phono MM, port USB, two inputs of the line, to be able to meet a wide range of possibilities for each listener.

The Cayin CS55A is constructed with a front panel entirely made of anodized aluminum, a vented frame with a beautiful finish, the more refined mounts available (and that is what made point to point by hand, entirely in the air), a circuit of the delayed start, to improve the life cycle of the toroidal power transformer and output transformers.

Thanks to the wide use of capacitors of high quality audio-grade, resistors film of carbon, socket, ceramic valves, this is the amplifier that every audiophile should have in their collection.

The impedance of the speakers may be 8 ohms and 4 ohms. Comes supplied with a handy remote control with all control functions.

Turn your music system! One extraordinary quality/price ratio and performance are the qualities that best describe the integrated amplifier valve Cayin CS-55A.

It is perfect for managing both the analogical world and the digital. In fact, the Cayin CS-55A incorporates a section Phono MM integrated that allows for the matching of the turntable and, at the same time, includes a converter USB DAC to be connected to a computer or a music server.

Through the USB input 2.0, the DAC is capable of playing digital audio signals up to resolutions of up to 32bit/384kHz, allowing us to listen to liquid music hd in high resolution..

This combination of the DAC is high end and valves allows to obtain a reproduction rich in harmonics and with a stage large and detailed, where all the layers of sound emerge with the exact plasticity.

The output stage can be switched between mode Triode and Ultra Linear. In addition, they can be used interchangeably, both power tubes KT-88, both EL-34 for an extraordinary flexibility of use.

On the rear panel of the Cayin CS-55A, in fact, there is a special selector that allows you to adapt the windings of the transformers for the alternative use of power tubes KT-88or EL-34.

In addition, a special measuring instrument built-in the adjustment of the Bias current in an easy, secure and autonomous.

A jack socket 6.3 mm on the front panel allows the connection of a headset and complete the standard equipment of this extraordinary amplifier valves, which, for versatility and performance, second to none.
