I was able to recently upgrade my surrounds on my 7.1 to Paradigm Cinema Speakers. I have Cinema 2 Diapols for the LS and RS, and regular Cinema 2 for the LR and RR, and I have to say, they work like a charm after calibrating them beyond the auto calibration my receiver did. I've started picking up sounds I didn't realize were there, though that wouldn't of been hard to do, changing from a set of Pioneer HTiB surrounds. Cheap ones, from Wal-Mart from about.. 7 years ago. They worked fine, but once I started getting into the big boys toys, I started realizing that they just weren't going to cut it anymore, so I found a good set, jumped on them, and am happy that I did. These will probably remain with me for a good long while, unless I decide to upgrade again.
