I have ordered a pair of Polk R15s off of ebay. I was wondering what kind of receiver to use for these speakers as I'll be using these hooked up to my pc. My budget for a receiver is $200, shipping included in the price. My main use will mostly be for music listening and movies, and the occasional gaming. I want to leave room for surrond sound in the future too, so a 5.1 receiver will be fine. I don't have a sound card yet, but will get one in the upcoming months. Any and all suggestions will be welcomed.
