300B COMBINED WITH CAYIN = TOPCLASS!

A-300B Mk2 is a SE (single ended) integrated class A amplifier, which also can be used as a power amplifier.  Power output is rated at 8 watts pr. channel but sounds like a lot more and it will bring you a sound that you will never come close to in a traditionel transistor amplifier. With 8 watts it can have a great impact which speakers you are using. Typical most people will look after some speakers with a higher sensitivity (92-94db and up), but even with a lower it will sound fantastic. Our own Zu Audio speakers starts from 97db and up, which definitely will be a great match to such amplifier (see them here)
