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!

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?

How can you run analog outs to a a DAC? DACs accept digital inputs.

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.

Sounds like you should use the digital out then.

I am doing the same with my Blu-Ray/HD DVD player with two channel PCM output over coax into my EMM Labs XDS1 CDP and it works extremely well. There is no need for a two channel specific track in your Blu-rays, every Blu-Ray player will down mix a multichannel Blu-Ray lossless soundtrack properly to two channel and should output to PCM 24/96 over coax or toslink for processing by a DAC. Further, the Oppo is said to offer a superior two channel down mix.

Of course you can, as long as you set the oppo in the audio menu to 24/96 as your output on the digital outs, you should have an option to out at least 16/48, 24/96, and I am not sure with the new oppo model but probably has capability to even output and upsample anything to 24/192...Which by the way it will upsample even a 16/44 CD to 16/48 or 24/96 with no problem as well so you can try it all ways to find out what you like or don't like about each.

However the second half of the equation and more import is does you dac truly support 24/96 or 24/192 at the input? Also you could have an upsampling DAC which means it takes the 16.44 or 16/48 signal from your transport and does its own upsampling automatically or by a switch on your DAC unit depending on the make and design. Also if your Dac only accepts a standard 16/44 or 48 at the input receiver chip and you set the oppo to output a higher rate it may reject it and not lock on at all meaning you could get a bit of a nasty sound thru your speakers or not work at all.

You will have to experiment to see what works best on your end unless you already know all your gear is capable.
