I'm getting close to a final decision on a new receiver. I'm using Polk RM6600 Speakers with a Polk PSW350 Subwoofer. It's between the HK 330, a Marantz 6300 or 5300 (both Refurbs) or a NAD T742. I'm more of an audio guy, but would like to enjoy my dvds in pretty decent surround as well. The system will ultimately end up in an 800 sq. ft. finished basement. Any help would be GREATLY appreciated. Thanks!
