Since the SP2 has no HDMI, I assumed the decoding would be done in the player and transmitting HDMI or analog could produce the same result from the BD player. It's also somewhat likely there are no level controls in the BD player. I know that is the case with my Samsung 2500 and my SP1.7 so I'm not sure w/o level controls any solution would work unless there were level controls in the pre/pro or there were no differences in levels from the listening spot.
