I have Paradigm Reference Studio 100s, and CC-570, and the 7100 does a fine job. I set the crossover to my powered sub at 80Hz so that I do not ask too much in terms of bass power from the front speakers.

The 100s are rated down to 28Hz, and I have suspected, though not proven, that 100 watts might not be enough for loud bass-heavy output from the 100s. (Yeah, I find it odd that I treat the 100s as "small" speakers, but that is what seems to work.)
