I was so impressed with the Denon 3802 that I got, that I picked up a used 2803 (almost the same). The 3802 is 110 watts per channel and the 2803 is 90 watts and a few supposed upgrades, including the remote.
The 3802 plays DVDs plenty loud at about -24 to -20. This 2803 seems to need to be on about -8 to -6 for similar volume. I doubt this is because of the difference in watts. The receiver display on the 2803 shows "M.Volume" when it gives the receiver volume. I wondered if there was some governor on the volume in the setup, which I haven't found yet.
Any help is appreciated while I download and print out the manual. Thanks.
