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

Vandersteen 2ce Signature (II or III; can't remember which). I let them go in 1990 because I was going back to school and couldn't fit them in a dorm room. They were the first speakers I ever owned that hung a solid, deep, tall image in front of me and sounded good with either chamber music or The Chambers Brothers. So when I got out of school and had room once again...

Bose 901's

Never sold a a pair.  However, I have upgraded with three successive pairs of

Magnepans.  Love them all.  

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.
