What piece(s) of gear did you sell/give away that you would like to have back?


We've all done it - sold or traded a piece of gear we had fallen out of love with, then regretted that decision at some point. If you could go back in time, but could only retrieve one piece, what would that be?

I regret selling my Spendor SP 100 Speakers. I loved them, but got the itch, as well as being younger and not as wise.
They were more colored in some ways than my current speakers, but it's all about enjoyment and involvement, and for that they were hard to beat.
Although I like my current speakers better, to me it's like different flavors of ice cream, and it would just be nice to have them around to use once in a while.  
JM lab Mini Utopias. I’m not sure why I got rid of them in the first place. Just the hope for more better I guess. But what is funny is thinking about the old great stuff I had in the beginning only to be disappointed when hearing it again. That’s happened on a few occasions.

Mint TD125 MKII w/SME 3009 arm. Same, gave it to a friend.
