Okay, first of all, thanks for taking the time to help
So for the past 4 years or so I have been using an Onkyo HTIB, specifically, the HT-S770. The specs can be found here.

To be quite honest, I have really enjoyed this little system but we now have a new home with a pretty good size living room (20X22). Needless to say, it's time for an upgrade because it just doesn't fill the room anymore and sounds really empty. I have been looking at a few options and would like everyones opinion. What I would like to do (right now) is replace the fronts, sub, and maybe the center. For the fronts I was looking at the Polk RTi10 vs. Monitor 70's vs. RTi8. Are the RTi10's hands down better than the Monitor 70's? For a sub I was looking at the Polk Audio PSW505 "12. Do you think these would fill this room nicely? For a center I was looking at Polk Audio CSi5 vs. CSi3. Is the CSi5 worth the extra 100 smacks? Let me just say that I do love bass, both in music and in movies. When that bomb goes off or that dinosaur puts his foot down I want to feel it
Now if you check out the link up top you will see the specs for the receiver that came with that HTIB. It says that it pumps out 130w per channel, which I was actually surprised to see that it was rated that high. Would that receiver be enough to power say two RTi10's along with a CSi5 or would I need to buy a separate amplifier and bi-amp them? Or do you think that receiver is a piece of crap and I would be better off buying a new receiver? A good receiver will be a bit pricey and may be a bit more than I would like to spend right now. If you think I need a new receiver, any suggestions for a great receiver and great price? Sorry for all the questions and believe me, I appreciate your responses. I am open to any and all suggestions so if you think there is something much better around the same price point then I am all ears. Here are the links to the products although I am sure most of you know exactly what I am talking about.
