Hello all so I currently running two rp280f up front with a rp500c. Using 4 rp500m for rears and surround and in the process of getting 2 new subs. I currently have been using a pioneer elite vsx lx101 that was actually given to me. For a free receiver I can't complain but I now have the opportunity to pick up a marantz sr8002. I know this is a better receiver but it'll cost me a cpl hundred which is fine I'm more concerned with will it be an upgrade? Is the extra power/quality something that will outweigh it's age and features compared to the pioneer? Will I actually hear a noticeable improvement? Please advise, thanks
