Hafler amplifier, onkyo pre-amp,plus relatively recent speakers from a surround sound (Sony) and a Panasonic 5 disc player. What do I get rid of them so that they don't go to a landfill?
Check your vintage record stores. Most will also buy used gear. And don't forget Freecycle.
You can get rid of pretty much anything in the Free section of Craigslist.

Geez, a Hafler amp? Does that gear work? If so I'd pay the shipping to take that off your hands. :-D
