which 5.1 reciever for B&W 602s?

I have B&W 602's for mains, B&W subwoofer, and Heywood rears. I would like to replace my prologic Denon reciever with a 5.1 reciever that can also run a pair of B speakers in another room. I would like to use optical input from both my Direct TV reciever and my DVD. I'm into both I'm approaching the my buget max already. Yamaha 630? Denon 683? HK? Onkyo?
I'm using a NAD T752 to decent results
NAD T752!!!!!
I'm using a Rotel RSX-1055 and 602S3's in my HT room. Sounds great.
