Cayin CS-55A KT88
Power and variety characterize this tube integrated amplifier. Its class AB circuit effortlessly lifts 2 x 40 watts to the gold-plated speaker terminals, which gives its owner great freedom in choosing a suitable loudspeaker. But there is also flexibility on the sources 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 conversion of digital audio signals with up to 32bit / 384kHz to the versatile integrated amplifier via USB 2.0. 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. There is also an external bias adjustment with a display instrument. An MM phono input is available ex works for a moderate surcharge. So everyone can listen to their own taste - if need be, 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 round off the harmonious overall package.
