Oppo BDP-83 optical out for 2ch stereo from blu-r?


OK, this may be a dumb question, but for the best sound from blu-ray (or dvd) discs should I go with the Oppo 83's analog stereo outs to my preamp, or use it's optical digital output into my outboard dac? Note that I do not have muti-channel capability, my stereo rig is 2 channel only. I am using the Oppo 83 for blu-ray, not as a cd player. For example, a concert on blu-ray disc. Would a HMDI audio de-embedder (hmdi-to-optical digital spdif) converter be something I should look into? Any advice on how to get the best 2 channel sound out of the blu-ray player would be appreciated.
Thanks!

Again, let me point out that for a Blu-Ray disc, the user must select the 2 channel sound track if that option exists. If not, the 2 channel output, analog or digital, will be a mixdown of variable quality.

With blu ray specifically I have not found this to be true, in movies it may have a slight effect on dialog, however 100% of the blu ray "Concert DVDS" specifically I don't have a single one that does not come with a 2 channel downmix in the menu..

Acutually from my experience so far with my setup which in the past was not true of standard DVD blu ray 2 channel even thru the digital outs does not vary at all from the multi-track option. Why? Not sure accept that in the new technlogy and format of making the blu ray discs they have seemed to somehow auto-sense regardless and your front 2 main channels are going to always be mixed with full range frequency.

Again this is not true with DVD, for example I can take your new Harry potter Blu ray or whatever which has Zero audio options but true HD surround or whatever and put it on with NO subwoofers, No center channel, and just running on the mains I still get as good or better explosion impact, and dialog with less channels and equal to running it thru HDMI to a multi channel processor! Since these revelations and the importance to me in specific of do I care as much about Transformers making it as accurate sound as possible like a mountain coming down in my house? I have decided movies are not that critical and the concert DVD's and music is far more necessary to get the attention and money.

Again this was never the case with Standard DVD, and definitely a KILLER with concert DVD's that if you were running the concert in 5.1 or 7.1 it sounded very hollow or totally aenimic in power output compared to using the 2 channel mix.

I am sure depending on the source, the processor, etc... This will all vary system to system to some degree. Again today digital has advanced far beyond 5 or 10 years ago and is cheaper, less and less issues with audio mixes have been the normal in my case recently with new releases over the past few years.
I have the same question. If I wanted to play Neil Young's archives in blu-Ray on my 2-channel system, can I just run the blu-Ray player through it's analog outs to the dac and realize 24/196 in 2-channel?
Sorry, I meant running from the blu-Ray player to the dac through the blu-Ray player's digital co-axial outputs rather than HDMI.
