Summary: I loved it while it worked but it died after 2 years. This is the second Denon I have purchased in 3 years and both died young. This one died after I lost my electricity but it was plugged into a good surge protector. The first Denon died after I lost electricity but it was not plugged into a surge protector. I am now very suspicious of the quality of Denon receivers!!!
Summary: I've owned this receiver for about a year and a half. In that time there have been 2 firmware updates. Neither went smoothly. I thought the box was toast after the first one, but it eventually recovered with some unadvised power cycles to kick it. The second never took. As soon as it starts doing the update the network link goes down and never recovers. I left it overnight but there was no progress, so I was forced to power cycle it.
