Speakers you regret selling


I was lucky to own Sonus Faber Extrema, Acoustic Energy AE1 Signature, and Dynaudio Confidence 5 in the past. They are rare in used market and can make any owner happy for the rest of his/her life. So I swore to myself I would never sell my Sonus Faber Amati this time though my wife has heard that a million times. What did you regret selling?

Original Harbeth P3s, in special edition wood veneer (the guy I bought it from said it was yew, but it looked like deep rosewood to me). Brilliant stuff, esp. with the Quad 34/306 amps I had at the time.

That was 5 years ago. I have since rectified the mistake by getting a pair a couple of months ago, with Xtenders. In cherry veneer, not as pretty as "the ones that got away".
Martin Logan SL3's... dynamics, bass & such was not their forte, however for this price range speaker paired with a good tube amp made magical music! The vocals, harmonics, timbre, etc. defied the price point of the total system!
