Greetings, I'l apologise right away for my questions, I'm just starting out in the Home theatre world! I have a 42" rear projection Tv arriving on Sunday ( ) it's High Def ready so I am looking to replace my Panasonic DVD Home Theatre System SA-DM3. I think I'm going to go for a PIONEER DV575 DVD player, but will need something for the surround sound. The speakers I have are already wired up and pretty much fixed into place, does anyone know if the either of these 2 systems will be able to use my existing speakers (they just have speaker wire so they need the Hi Fi type speaker clip connections) YAMAHA RXV350 A/V RECEIVER PIONEER VSXD514s Also what is the difference between an amp and a receiver? Am I looking for the right equipment here?
