An exceptional stereo power amplifier on many levels -- high-biased MOSFETs providing higher-power class A operation, direct-coupled front-end circuitry for exceptionally high stability and larger, more robust heats sinks similar to those of the larger .8 amplifiers. The list goes on, but listening may tell you the XA30.8 represents a value high-point -- quite possibly your particular optimal balance between performance and cost. Demo unit perfect working condition with only slight signs of use. Complete with boxed manual and remote power cord.
