Hey guys, Im a college student and will be moving into an apartment in a few months. Right now Im thinking of purchasing the AR HC-6 set since I have heard great things about them. What receiver would you guys match up with this set? I initially was looking at the HK 520 but the lack of a B set of speakers disappointed me. Hopefully, within the next year we will move into a house and I hoped to use the B channels to hook up speakers on the porch. Im looking to spend no more than 500-600 bucks on the receiver so shoot me some suggestions. Also, are there sets better than the Acoustic Research in the same price range? Thanks!
