Haven’t hear 2’s, but I heard the Sopra 3’s at my dealer’s in a medium-sized room (maybe around 16’x20’ with high ceilings) and was fairly well impressed, and I’m a die-hard Tannoy guy who didn’t like the bigger Utopias. The Sopra 3’s sounded awesome! And apparently their sales are brisk. Hell, I almost considered it before I stuck with Tannoy and went for the Canterbury GR.
Sopra 3's sounded well balanced and musical, with great technicalities, and worked well with the room. To be fair, the hardware behind them was rather pricey -- current model VAC separates (phono/pre/power), Critical Mass Systems rack/filters, Clearaudio Master Innovation table, Shelter Harmony cartridge, AQ cabling. But these days, you need that kind of gear to fully tap into a great speaker’s potential.
