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.
