Cayin CS-55A

  • 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.
  • Transform your music system! Extraordinary value and performance best describes the Cayin Audio CS55A Integrated amplifier. As the centre piece of any system, the unit is at home with both analogue or digital formats. CS-55A includes a built in MM phono section to accommodate turntables and a built-in high resolution DAC for use with computers. Via the 2.0 USB input, the DAC is capable of covering digital audio signals up to 32bit | 384kHz. This combination of a high end DAC and tubes makes for a rich and detailed soundstage.
  • The output stage can be switched between Triode and Ultra Linear mode and either KT88 or EL34 tubes can be used for the maximum amount of flexibility. A headphone jack on the front completes the unit and makes this one of the most versatile and compelling products on the market for 2016.

well done

I have been pleased with build, sound and ease of use.

Rare Gem

This CS-55A amp has been positively reviewed from several YouTubers so I was expecting it to be good. However this thing is much better than I expected which seems odd given my initial expectations. Build quality is first rate besting my McIntosh gear and the sound quality as well. I had to put new Golden Lions in my C2200 just to keep up with this CS-55A and still the CS sounds more extended, detailed and textured. It's THAT good. And has no problem driving my Aerial Model 8B's at 86db efficiency at 4 ohms. My MC 402 only beats it in shear power output and bottom end control however the CS-55A is every bit as extended. Considering the price for this unit, this is one of the best bargains in HiFi. Just get one before they raise the price. Thank to Misicteck for a smooth trouble free experience where all my questions were answered on line within minutes. The amp arrived in perfect condition just 5 days after purchase. A+ Thank you so much I will be back. Please consider offering more good gear from Asia e.g. SoundArtist, Denafrips, Dodge, Line Magnetic and Shanling.
