not to get too far off your topic, but I have the 604 sII for fronts and 602 sIII for rears. The old 604's are great for floorstanders and I have to say it's almost a crying shame to use the 602's as rears. They sound so good for something so small (compared to the 604 anyway). Hopefully you can compare the Paradigms and B&W's in the same store. There is a quite noticable differnce (not better or worse; just fitting to different tastes).
