Need some advice: Found some Audio Equipment

Send pictures to tmraudio.com and see if they make you an offer, is my best suggestion 

You can always eBay them and try and get a couple of hundred dollars, especially the SCAMP power amp.  Or donate them to Goodwill, or to a neighborhood kid who has nothing.

Check current prices on hifishark

Quick drill about, imho:

Sell as a set, some bits could draw... ;)

You can also look into FB Marketplace. If you use a little common sense, it is fairly easy and safe.

Parasound seems to sell very well on ebay...someone wants that gear you have...not worth very much, but enough to make selling worthwhile, that older Parasound gear is popular...
