I'll say it again, especially with that nice Paradigm sub, I think the system you've described is going to be fantastic! Also, a lot of people seem to really like the HK receivers, and they are often available for good prices from harmanaudio.com and other online sources. Don't get me wrong, I personally have Denon and Yamaha stuff, but there have been numerous mentions by people who really enjoy the HK multichannel processing.

Now, go have a beer.
