I regret some room/speaker combinations I've lived in more than the speakers themselves, as they were chosen for a specific living environment i.e..Totem Forest's @ my condo, Totem winds/Wilson 6's/Martin Logan Odyssey's at my previous large house. My first pair of high end speakers were the Dunlavy SC-V's which were great for re-creating a large dynamic and realistic soundtstage..they just didn't quite do it for me on symphonic material, otherwise I may have kept them and never moved!
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?
