Cayin CS-55A tube integrated amplifier KT 88

Cayin CS-55A tube integrated amplifier KT 88

Description

Power and diversity characterize this integrated tube amplifier. Its Class AB circuit effortlessly lifts 2 x 40 watts to the gold-plated box terminals, which gives its owner great freedom in choosing a suitable speaker. But there is also flexibility on the source side: vinyl lovers can use a separate phono board or order the Cayin CS-55A with this option. If you want to use your computer as a source, you can transfer the versatile integrated amplifier via USB 2.0 to convert digital audio signals with up to 32bit / 384kHz. This combination of high-end sound card and classic tube charm can also be customized. The output stage can be switched between triode and ultra-linear operation, and another switch allows the use of EL34 or KT88 tubes. On top of that there is an external bias adjustment with display instrument. An MM phono input is available from the factory for a modest surcharge. So everyone can listen to their tastes - if necessary, even with headphones. There is a large jack socket on the solid aluminum front. Selected components such as the encapsulated Alps potentiometer or ceramic tube base complete the harmonious overall package.
