Others have covered the technical limitations/features of the receiver - let me put a word in about audio quality.

It's really astonishingly bad. I mean, I'm picky about sound quality, but not that picky - but the difference was night and day between it and my little T-Amp. The T-Amp was like crystal in comparison - the Sony 520 had absolutely zero imaging, obviously bad stereo crosstalk (how often can you even hear that??), clearly introduced signal distortion... I could go on. The sound was essentially dead. Amplified, but dead.

Opting not to kill my beautiful music, I went with a 1-year old used Yamaha HTR-5960 and couldn't be happier. The amplifiers in the Yamaha's are clean and clear. But then, at a price point this low, any amplifier is probably going to be less than great, and you do get what you pay for - I was just surprised that I could hear it with such clarity (or lack of clarity, as it were). I can't recommend this if you have good ears. You have been warned.

Pros: easy set up. So far seems good for the price. Good enough if you are looking for easy setup & easy handling for a decent sound.

Cons: seems that the HDMI inputs & out put is not really nessecary as you still need to hook up optical connections for the audio to be heard.

Notes: you will need a subwoofer with a RCA cable hookup & optical cables inorder to receive audio as the HDMI inputs are only "passthrough" & carry no audio signals.
