I saw an entire vintage Pioneer system at the local Habitat for Humanity here, going for $200 complete. What do these hpm speakers look like? the system I saw had some pretty big woofers with the mids off to one side, cabinet was quite wide(a-la '70's) maybe 16-18" wide by about 3ft tall, not all that deep. Didn't see what the receiver was.

Half of communication is listening. You can't listen with your mouth.
