Summary: After only 2 1/2 years our beloved Onkyo SR707 receiver stopped producing all sound - as I came to find out is common with them (besides also running quite hot). I knew Denon was a reliable, well-respected brand from my research the last time, so I decided that would be the way we'd go this time. The reviews for this receiver are quite glowing and after a few days use here is what I think. The sound is very crisp - which is really nice for trying to hear dialogue.
Summary: UPDATE on AUgust 30. After a month of very little use, amplifier is presenting various problems: 1. And most critical, it is suffering from overheating. after 5 or 6 hour use, it resets and locks itself. I never use it at more than 50% power, it is placed on a very open place with lots of circulating air. 2. Airplay is unstable and will never play fo rmore than 45 minutes before I need to restart the MAC and AMP 3.
