Hi there. I'm thinking about buying a dvd/audio system with an A/V receiver, DVD player, 2 speakers and a subwoofer. I wonder if anyone can tell me about a good A/V receiver in the market. I've heard lots of good stuff about the Yamaha AV-RXV640RDS, but i'm new to this stuff so i don't know much about good/bad brands/models. Anyone can help me? Give me some sugestions? 3 other A/V's in my list are Denon AVR1604, Marantz SR4400 and NAD T742. What do you guys think? Thanks a lot.
