Cayin CS-55A Integrated Amplifier

The CS-55A is the most recent advancement in tube amplifier technology created by Cayin. This state-of-the-art machine boasts forty watts per channel by using 4 KT88 tubes in Class AB ultra-linear push pull amplification. The CS-55A consists of four pairs of input: one Phono, a 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. Similarly to the A-88T, the CS-55A comes with a handy remote control.
