re: AA-16400

Pulled Heath 1600 out of stash so I could clean relays (critical on old amps) on Mitsubishi DA-15. Running Sony STC 7000 to amp to Bose 301's. Right of the bat, highs were tingling. Very noticeable. Listening right now, very detailed, nice bass, not over powered. I need to start swapping more. Merry Christmas~ I'm sorry I see this is for AA 1640. Well here's one for AA 1600.

This amp works very well with my Maggie Tympani's, much to my surprise and delight. I tried several other large and seemingly more appropriate power amps but the Heathkit just kept sounding better. Lessons learned of how speakers chose their amps.
