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

I had Advents, Dynaco 25, 35 & 50, ADS 620, all of which are long retired/gone (40+ years).  I consider someone keeping the older set rather than repurchasing it satisfactory for this forum discussion.

No, it isn’t satisfactory, because that was not the question. You're just listing a number of speakers that you own. Completely different thing.

Quad S-5.  Been trying to find a pair again ever since. 

B&W DM23...Yes, I am older than dirt.   : ^ )

ADS L980
Oh man.  Ten years ago found a pair, near perfect at a steal.  I really liked these (my first ADS) but knew I could make bank by reselling them. I did and IMMEDIATELY regretted. I tried over the years to buy them back, but nope. 

Found a pair this early spring for a more than fair price and went to his house at 8AM the next morning.  Original owner and in near perfect shape.  I will not let these go.  They are at Richard So's getting a renewal. 

These are not the best ive ever had but man do they sound correct
