You should be able to get the Marantz SR5004 for under $1k. I paid $900 with tax for mine. I haven't had a chance to hook it up yet, waiting on speakers. Nonetheless, I went with it over the Denon because of the 3 year warranty that comes with the Marantz. Not certain about the Denon 3310, but the 2310 that I was considering doesn't have pre outs. The Marantz 6004 does have bluetooth capability built into it. I can see this becoming standard on receivers in this price range. The 5004 has the capability, but you have to buy the remote seperately.
