My wife found a pair of 30+ yr old HPM60s down the street from our house the day before trash day - we picked them up, and damned if the things didn't still work. Passed them along to an audiophile friend who says they sound surprisingly good. (No surround rot, or bad caps in the X-O)

Can't beat that! I saw a whole world of speakers, receivers, and amps blown up by heavy-(volume)handed users back in the late 70's as a repair tech.
