Power and variety characterize this tube amplifier. Its class AB circuit effortlessly heats 2 x 40 watts to the gold-plated speaker terminals, giving its owner great freedom in choosing a suitable speaker. But there’s also flexibility on the source side: vinyl lovers can use a separate phono board or order the Cayin CS-55A right away 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 individualized. The output stage can be switched between triode and ultra-linear operation, in addition, 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 ex works for a modest surcharge. So anyone can listen to his taste – if need be, even with headphones. On the massive aluminum front there is a large jack. Selected components such as the encapsulated Alps potentiometer or ceramic tube base complete the harmonious overall package.
