Hi guys, so I recently came into a pair of Polk Audio Monitor 70's. First off, any reviews on these or just on Polk Audio in general, I heard them for a minute and they sounded good but I pretty much know nothing. I am looking to buy a receiver and have no idea where to begin. I was hoping to find one for around $250 but willing to wait a little and spend around $500 if necessary. I am going to be adding on a center channel and subwoofer eventually so I need the receiver to be able to handle all of those. Thanks in advance for any help.
