Don't really follow Paradigm, I assume that you are referring to the Monitor 7 v6 vs v7 ? About the only thing I've heard is that the bass on the v7 is a little looser/boomier than the v6 and that the v7 is a bit more neutral and not as forward as the v6. Doesn't really sound like one is better than the other, depending upon your personal tastes, just slightly different.
I have a full monitor series 7 setup with a studio sub 12 and love my setup. I can run the monitor 11's full band but choose to have them crossed at 80 hertz. Never listened to the previous series though so could not say which series was better. Music and movies do sound great off them in 2 channel full band with no sub I just like the sub.
