Understood. I will always regret having tossed a pair of Stereo70s from If my third floor window into a dumpster while preparing for a house move about 30 years ago.
That's terrible, but I've been there. Off the top of my head, mostly because of moves, I've chunked:
Thorens TD-160 (didn't like it that much so it went in the bin); Technics SL 1100a (I had two, don't ask why--still have one, though); Garrard Zero 100 (have another I recently restored); Counterpoint SA-3 (actually gave it to one of the moving guys because I didn't have time to replace some caps and he said he'd take it); Dual 704 (gave it to a friend who owned a record store--just restored another because I liked it); Yamaha TX-950 tuner (FM? What's that?); Pioneer SA-9500 that was beginning to act up... Probably a lot more if I thought about it longer.
And I've sold for next to nothing ten times as much. LOL
The only thing I really regret and wish I had back is when my ex left me, taking a Pioneer SX-1980 out the door. Um...I mean the Pioneer...not the ex.
