The CS-55A is the latest innovation in tube amplifier technology from Cayin. This cutting-edge amplifier delivers forty watts per channel using four KT88 tubes in Class AB ultra-linear push-pull amplification. It offers a wide range of connectivity options, featuring four input pairs: one Phono, a USB port, and two line inputs, ensuring versatility for any listener.
Crafted with a fully anodized aluminum front and a beautifully finished vented chassis, the CS-55A combines the finest hand-made point-to-point wiring with a soft-start circuit that extends the life of the toroidal power transformer and output transformers. With high-quality audio-grade capacitors, carbon film resistors, and ceramic tube sockets, the CS-55A is an amplifier every audiophile should own. The speaker output impedance can be switched between 4 ohms and 8 ohms, and, like the A-88T, the CS-55A is equipped with a convenient remote control.
Elevate your audio experience! The Cayin Audio CS-55A Integrated Amplifier offers exceptional value and performance. Whether you are using analogue or digital sources, this amplifier is the perfect centerpiece for any system. The CS-55A includes a built-in MM phono stage for turntables and a high-resolution DAC for computer use. Through the 2.0 USB input, the DAC supports digital audio signals up to 32bit | 384kHz, delivering a rich and detailed soundstage when combined with tubes.
The output stage offers flexibility, allowing you to switch between Triode and Ultra Linear modes, and you can choose between KT88 or EL34 tubes. Additionally, a headphone jack on the front completes the package, making the CS-55A one of the most versatile and compelling amplifiers on the market today.
