I know this thread is a little old now, but ended up with SA-35 in walls, CC690 and a Sub12 with 3 more Paradigm speakers in the rear. The Sub12 is the cleanest bass I've ever heard. I'm old with old, beat up hearing, so take that with a grain of salt, but it sounds amazing. My 12 year old son with his hip-hop iPod, I have to pry him away so I can watch TV.
