Hi, I am new to making a home theater setup and need some help. The system I will be setting up will be a 5.1 system which will include: RP-600C, x2 RP-800F, x2 RP-500M, and a SVS PB-2000 Pro Subwoofer. I am not sure what receiver I need to power this speaker system setup. How many watts per channel do I need to effectively run this system? This home theatre setup will be used for gaming and watching movies. I hear Marantz and Denon are great receivers just not sure what size I need. Any advice would be greatly appreciated.
