5 out of 5 eggsExcellent... So far

Pros: Video and sound quality.

Cons: None so far... We'll see what happens after 1 year.

Other Thoughts: My last Onkyo receiver died (the HDMI ports stopped passing video, no internet connectivity and not starting correctly) after 1 year... Exactly 1 week after warranty expiration. Luckily, I had bought extended warranty so I got my money back and, given I really liked the old receiver, decided to give it another try with a newer version (and extended warranty again, of course!)
