What equipment do you most regret parting with??

A Threshold SA3. Bought some panel speakers and thought I'd never only need 50 watts again. I think this is the last piece of equipment I have sold (over 17 years ago). Never made that mistake again, but are my closets full of stuff! :-)

Verity Audio Fidelio's in the makore finish---I bought another pair and will not part with them!!!!!!!!!!!!!!!

I regret selling my Teledyne AR-9 Speakers, mostly because I had to give them away because of Bluebook Value,
still wish I had room to store them.

My Linn Sondek/Ittok turntable/tonearm. I gave it away for almost nothing.

Vendetta Research phono stage! What was I thinking!
