I was using a NAD 3020 as a preamp with an early PS Audio Power Amp (can't remember the model) in the late 70's early 80's. Great phono section and the 80 WPC amp pushed any speakers I had. The 3020 was utterly unreliable but I fortunately worked for a large appliance retailer with a decent service department. That early PS Audio amp was relatively affordable, back then.
