Cayin’s hybrid circuitry utilizes the best of both stereo worlds, in an aesthetically-pleasing brushed aluminum industrial casings, with the matching blue-lit power meters on the front to provide accurate usage tracking.
“H80A fulfilled its promise of delivering the best of tubes and the best of solid-state.
The Cayin CS-55CD is a stand-alone hybrid tube CD player developed to partner with the CS, MA and LA series integrated amplifiers. D/A conversion is accomplished by a Texas Instruments PCM5101 chipset, while the CS-55CD’s analogue output stage uses a 12AU7 tube. The CS-55CD utilizes a high-speed USB 2.0 receiving and decoding 32bit/384kHz high resolution digital signals together with high-quality audio operational amplifier circuits, with included USB input and remote.

The CS-55A is the most recent advancement in tube amplifier technology created by Cayin. http://en.cayin.cn/products_info?itemid=84 It 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.
The CS-55A comprises of a fully anodized aluminum front, a vented chassis and a soft-start circuit to enhance the life of the toroidal power transformer and output transformers. 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.
The 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.
The output stage can be switched between Triode and Ultra Linear mode and either KT88 or EL34 tubes can be used.
KT88: 22W Triode – 40W Ultralinear
EL34: 20W Triode – 38W Ultralinear
KT88: 5Hz – 44kHz (-3dB)
EL34: 5Hz – 48kHz (-3dB)
