I'm looking for a reciever, i'm thinking the 500$ range. I originaly was going to get the Onkyo 595, but then loooked at the Marantz 5200, and I like that it has 6.1. Any suggestions about these? I haven't seen hardly and reviews on the 5200. Also are there any Denon, or maybe even Kenwood, Yamaha or Pioneer that are around or under this price range with 6.1?
