I recently auditioned Paradigm Studio 20s / B&W 603s / and ended up buying Quad 21Ls (would've got the 12Ls but got a great deal from www.canadianhifi.com on the 21s)
I was completely unimpressed by the Paradigms, the B&Ws were nice, the Quad's (11Ls / 12Ls / 21Ls) were all gorgeous.
I would highly recommend auditioning some Quad's if you get the chance I also am simply running the two fronts but (and i have run 2 channel in the past for dvd movies) I am not missing my center channel for DTS movies (DD movies a bit) I cannot believe how amazing these speakers are for dispersion and all dialogue is perfectly centered its incredible.
I picked up my gorgeous piano black 21Ls for $1200 CDN.... ;) (Ask for Rob @ Canadianhifi)
Hell, my girlfriend spent the day after the purchase telling her friends how much she loved my speakers (and she's not generally into that kind of stuff)
Those are my thoughts anyways.
