I’ve got about 10 hours of use on the 3808ci and M80’s. So far, so good. It seams to have plenty of headroom at reference levels. I’m still playing / tweaking, but I’m pretty impressed with this receiver. The GUI is wonderful and works perfectly, at any resolution, and does nothing to the video stream to degrade it (that I can tell). As others have said about Denon many times on these boards, and a sad fact that I have come to appreciate, is that Denon manuals “SUCK”. It’s easy to read, but is sure does omit a whole hell of a lot of pertinent information that the user just has to sorta figure out on their own.
