Could it be that there are more dacs in the output stage, bigger power supply, etcetera on the Denon AVR, even though they could be inferior to the type in the OPPO unit? More testing over the next couple of weeks will have to be performed in order to verify just how much the difference is.
Unless you engage the pure direct audio mode on the 3808, the analog outputs from the BDP-83 go through the BDP-83's DAC's, get converted back to digital by your 3808, sent through the 3808's bass management handling, Audyssey is applied if turned on, and then through the 3808's DAC's to pass along to the internal amplifiers. If you use HDMI, you eliminate the DAC's in the BDP-83 AND the analog to digital conversion in the 3808.
If use the analog outputs on the BDP-83 and select the pure direct audio mode on the 3808, you lose the flexible bass management, Audyssey, and other processing features the Denon gives you.
The DAC's in your 3808 are, IMHO, at least as good as the DAC's in the BDP-83 but give you FAR more flexible bass management and lots of other goodies that the BDP-83 doesn't have (Audyssey, etc.). I see no good reason at all to use the BDP-83's analog outputs with as good as the 3808.
The bottom line is this:
If you have an older receiver / processor that doesn't have HDMI inputs, then by all means use the BDP-83's analog outputs. In nearly every other case, I would consider HDMI to be the better choice.
