Sorry, this Product is no longer available.




Yet another built-like-a-tank, classic-looking tube integrated amp from Cayin. The 688R integrated is a true dual mono design, with a potted toroidal power supply and potted output transformer for EACH channel. This 78-pound beast is even more powerful than the Cayin A-88T integrated, and that thing is no wimp.

The 688R is loaded with eight KT88 output tubes used for Class AB1 push-pull amplification. Output impedance is selectable, with 2, 4 and 8 ohm taps, allowing you to fine-tune your speakers. It's also switchable between Ultralinear and Triode output modes. A preamp input allows the 688R to function solely as a power amp if that's what you desire. Otherwise, four 12AX7s and two 6N6s are used in the built-in preamplifier. And the faceplate includes tone controls for both treble and bass, a novelty in today's audiophile world.

The 688R includes quality point-to-point wiring with premium capacitors and resistors. The unit is remote-controlled and comes with a detachable IEC-type power cord.

Easy on the eyes, ears and wallet – that's Cayin.
