Can't say I've owned all that many great speakers. Last ones were Accoustats. A couple of years ago I decided I wanted to put together a serious music system. Spent many hours auditioning a lot of gear. Some of the speakers getting on my short list included Sonus Faber, Cremona, Auditor, a number of Aerial Acoustics models, various Thiels, Magnepan 1.6 and 3.6, too many B&Ws to count, Dynaudio Contuurs, Totem Hawks. The ACI Sapphire XLs kept popping up in a lot of threads. I can't tell you how glad I am that I heard about them!
