I am a newbie to HT/Surround sound and I recently started looking for a 5.1 system. I decided to buy a pair of RC85i's for front surrounds and RC80i's for rear surrounds with a PSW10 sub. Still deciding on the center. I am trying to figure out what receiver to get that would match good with these. I am looking at $500 and below. Would a $500 receiver be overkill for these speakers? Any recommendations? Thanks!
