I think you are going to find that Paradigm speakers, as with many other similar brands like Energy, psb, etc., will sound great with a very wide range of receivers / integrated amps / power amps.

I have a pair of Titans in my kids' home theatre as the front mains, driven by a 100 Watt Yamaha receiver and they (the Titans) love it. I also installed a pair of Titans in a conference room at work where I show the occasional noon movie, and there I drive them with a 30 year old Yamaha 15 W/ch receiver - and they sound just fine as well.

Bottom line is that, except for perhaps a slight increase in perceived output level (on top of already high levels), making the jump in amps is not going to net you an awful lot. Mind you I also believe that if you can get it cheap, there's never anything wrong with having more clean power available to drive any speaker.
