I have a secondary system, the heart of which, is a 1970s Sherwood 7100 receiver. The thing is a little killer and has a VERY good headphone amp to boot. The one I have was bought at Goodwill for $20 and works perfectly. The 7100 has a sound that is tube-like in nature. The 7100-A has more of a solid-state sound. Both receivers make for good music.
