If this is the late 70s high end from JVC, then pass on it. Just another bright, hard amp. Forget "class A" as meaning anything translating to musicality - meaning, once you put the amp in, you forget "auditioning" and . If you want affordable performance from the 80s - DENON POA 1500, 4400A, 6600A, YAMAHA M4, M2, Tandberg 3000 series. Cheap great bass: yamaha 2200 pro amp, oldest Brystons.
