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

Martin Logan Monolith IIIx.

So frickin' cool looking.
Never really got them to sound good, but, hey... 

Sold to a guy in Japan and made money on them. So... mixed feelings.

At the moment, I don't think my Vandersteen 5 speakers are going anywhere soon.

I had the Spendor 9/1's for several years after selling the SP100's. I upgraded the crossovers and wiring myself, but in the end, I always felt more affection for the sound of the SP100's. They are very good speakers though, and really beautiful. People would comment on their appearance.

Infinite Slope Model .6 which I had lusted over since college days.  Finally bought a pair, but sold them for some Axiom M80 towers.  Big mistake.  Bought another pair of the .6 (actually two pair) along with ultimately a pair of Infinite Slope Model 1 and then the Model 2's.  Eventually sold them all and moved on to Focal.  The Model 1's were the favorite of mine out of all those products.  Too dated of styling though for me anymore, but they went to a good home.

Late 80s Infinity Kappa 9s, best rock speakers I’ve ever owned…..good even with crappy 80s and 90s recordings 

Magnapans, don’t remember the model, had kids and they had to go. Now I’d love a pair again but with two giant Maine Coon cats and a 105 pound Golden Retriever I just know they get damaged.  Maybe some day…
