What speakers have you mistakenly let go and then later repurchased?

Thiel CS something or other, but really good

Tonian Labs TL D-1

Owned a pair, sold them, then missed them. Then bought another pair. If they would have went a little louder without breakup. I would have never sold them.

Harbeth P3esr in my second system. There was something unassuming yet special about the speakers. I’ll probably buy another pair next year. 

spendor sp100's - but i did manage to get the back in the fold... 😁

oh man, i had an acoustic 320 and 2x15 cabinet, bought it for $400 in 1990 or 1991...a few years later pawned it. then bought it 10 years later from a completely different pawn shop. walked in lookin for something else and couldnt walk out without it. fantastic amp. got a 370 also, which, til it blew, sounded even better.

Whoa. Cey, all I had to do was call the buyer, you sent that amp out into the world!

Russ Alee designed some interesting gear. That 320 is similar to the little Acoustic Image Focus 2R I currently use. Mic and Instrument channels and a master out for the Upright. 

I had the internal amp and the Gene Czerwinski 18" driver rebuilt some time ago but it hasn't been out of the house in decades. Crazy loud.
