Budget Power Amp and Subwoofer Suggestions

Hi- I'm looking for some ideas for a fairly modest HT power either in the form of a 3 channel and separate 2 for surround or all 5 channels in one. I also am looking for an appropriate subwoofer. I'm planning on buying either a Marantz or NAD preamp new/ year old. I will consider both new and used amps, plan on spending between $1200 and $1500. I will be driving B&W CM series 1st gen (CM-4, CM-2, CMC) in a 17'x16' family room with a 103" projector. The system will be used for everything from everyday TV to movies, sports, and a little bit of gaming and rarely for Blu-Ray audio or SACD (most of my music is on a 2 channel system in my living room). Any suggestions will be appreciated.
