Help with Oppo BDP-95 dedicated stereo listening set up

Need help with oppo 95 dedicated stereo outputs. I have the player connected directly to my Emotiva amplifier using the XLR outputs. In the audio set up, I am not sure which stereo priority I should be using, front Rt/Lt or down-mix stereo in order to utilize the dedicated stereo DAC. One thing I have noticed is that the volume is slightly higher when the priority is set to down-mixed stereo. The manual states that original stereo is not affected by down-mixed stereo, but does not mention which is preferred for dedicated stereo listening. I would appreciate any suggestions.
Thanks in advance!

Thanks that is a good point. I am going to call oppo tomorrow

It works great given you power amp has high enough input impedance, usually >20 kohms. To use it you need to have your oppo volume on variable and change it with the oppo remote. Previous oppo models like the 83 had trouble with this set up, but the 95 works like a charm. Some people may not like this since they are used to the coloration introduced by the preamps. Personally I do feel that the oppo sounds a little to bright directly into an emotiva amp. However, this set up should still be optimal theoretically, again considering you amp has high enough impedance to avoid roll off at the bottom end of the frequency
