So will that work considering the oppo 105 has a better DAC and will enhance the SQ or I won't gain nothing and won't notice any improvement in the SQ,and would be better of going for the 103 and connecting it via HDMI?
I'm not sure what you mean by "analog pass thru" but the 2808CI has a set of multichannel analog inputs that are compatible with the Oppo's multich output. These multich inputs bypass all digital processing and go straight to the amps, thus avoiding the Denon's DAC's, so if that's what you mean by "pass thru" then yes, it has it.
You can combine these multich inputs for audio with the video of any other input, by switching the input mode to EXT IN.
The thing to note however is that, when bypassing digital processing, the receiver basically turns into an amplifier only. The player serves as the "processor", providing all audio decoding, bass management, etc. That means you lose the benefit of the receiver's digital processing, especially the Audyssey room correction.
So essentially it's a tradeoff where the plus side is potentially slightly better DAC's on the player side, but the downside is the loss of room EQ which improves your acoustical response. By and large, the latter is much more important than the former, which is why the 103 is the better buy for modern HDMI equipped digital receivers. The 105 is really intended for the "audiophile" buyer who has an older, non HDMI amp or a high end analog setup.
