The State-of-the-Art Cayin CS-55A Tube Integrated Amp boasts 38 watts per channel, a USB DAC, Phono Output, Front Headphone Output and a Sweet, Sweet Sound!

This beautifully crafted hand made amp is designed to deliver the wonderful sound of the original classic Marantz amps with features and build quality that would not have been dreamed of in the 1960's or 1970's. Although many 'improvements' have happened to HiFi equipment, many purists still believe that Simple is Better. Classic, simple design of amplifiers, with the improvement that better capacitors and better connectors, and even creature comforts like Remote Control, will reproduce your music in an easier to listen to, less fatiguing way.

The Cayin CS-55A Tube Integrated Amp is a state-of-the-art machine which boasts 38 watts per channel (40 watts by using four KT88 tubes!) in Class AB ultra-linear push pull amplification. The CS-55A consists of four pairs of input: one Phono, one USB port, and two line inputs giving a wide range of options for any listener.

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.

The removable cage snaps on and off anytime. Cover on has a clean classic look, cover off... Keep On Glowin'. The Cayin CS-55A has a built-in phono stage as well as a dedicated headphone output. It also has a 32-bit/384kHz USB DAC, so you can connect your computer to the CS-55A and stream music through it.
