Andrew,
I have Paradigm Reference Studio 60s, CC-450 center, ADP-350 dipole surrounds and a pair of Reference Studio 20s in another room. I couldn't be happier. Take a look at the Paradigm Reference series stuff. Paradigm products typically [in my opinion] out-perform more expensive speakers made by other manufacturers. Very clean, very nice soundstage, airy highs and solid bass (although even with the Studio 60s, I'd recommend a sub). Drop me a line if I can answer any questions for you. Good luck!
