Have not heard the Paradigms. I liked the KEF Ref3 more then the Sopra 2, wider soundstage with a better 3D imaging, plus I liked the tone of them a lot more. Also, the Dynaudio Confidence C2 or the Raidho XT-2 would be highly recommended. I own Dyns right now but at this point I think if I was gonna spend that much I'd be between the Raidho and the KEF.
