I have head both. The Polk was on a reciever (denon I believe) and the Paradigm was in Arcam preamp/amp (don't know the model). It was also a while ago so take my coments with a grain of salt.
The sound quality is comparible and it really comes down to personal taste. The bass is puncher on the Paradigm 100s. The Polk had a lot of bass but it was not as quick and seemed to cover up the midrange a bit. The highs on the 100s are a lot more forward than on the Polk. While the Polk's highs were good they are a little laid back for my taste ( you might like them... They have good detial).
All in all both are good but the Paradigm were a lot more interesting and fun to listen to for me. I like a some what forward and neutral speaker so YMMV.
Try and give then both a listen.
