I am very interested in Final and Potpori. I currently have been running XStatic full-range electrostats for 30 years and am a total flat-panel dipole fan. Last year, I updated my old Velodyne subs to Rhythmic and found that to be a superb match. At one time I toyed with the idea of going to the ML Renaissance 15A, but after comparing them side by side, I elected to stick with my XStatics.
I heard the Potpori at the Florida Audio Fest last spring and was quite impressed. I've not heard the Final.
I'd be keen to hear form anyone who has heard them compared to the ML.
