I still have my Adcom GFA555 amp that I bought new many years ago. I'm actually using it in bridged mono to drive my center channel speaker. Also has some B&W DM302 bookshelf speakers that I wouldn't sell. They are sitting in their original boxes. My Von Schweikert VR-4s are sitting unused, but I'm saving them for my son. He has no room for them now.
I used to have a pair of five sided dbx speakers. They had tweeters on 3 sides. Real walnut veneer. Probably not amazing sq, but very cool. I wish I still had them.
