This is one of B&K's strongest amps from the 90's with 200 watts x 2 channels of
super-clean MOSFET amplification. The Sonata series was regarded as among their
best designs and this quasi-dual mono beast was no exception. It's in very good shape
with a clean chassis and faceplate although the lower left corner of the face was dinged
a bit during shipping and carefully removed and straightened. Notice the balanced inputs
as well. I'd keep it but I really have no use for this much power.
