There's a few reviews out for the Sony. Most like it and have good things to say about its audio quality and it seems to be pretty powerful for the price. Plus built in wifi and BT can't hurt. The GUI is rather old and slow and there are reports of it being slow to complete the HDMI handshake when switching sources.
I would get the 717. It's a much better receiver than the 616 and the 1122. Especially since I think Pioneer moved all their models down, the old 1021 is now the new 1122. I'm very disappointed in their 2012 line. My cousin has the 709 (precursor to 717) and I'm really impressed with it.
