Have not tried my amps with the 3808 yet, the 3808 sounds great. With my 2805 there was minimal difference at low to moderate levels. Where you noticed the amps was when you cranked things up, in my opinion.
One thing that is frustrating, and maybe it is just me, but on my 2805 remote I could cycle through music/cinema/games mode when set to Dolby PLIIx mode. Seems to be a little difficult figuring this out on the 3808, so far I have to go into the GUI to change it manually, which sucks.
Also, I need to get a HDMI cable to go from my HTPC video card to the Denon as I only have one to the projector. I'm currently using Component out on the Denon to my projector...
