You can. I would prefer using digital coax (or, better yet, HDMI) to take advantage of the DSP in the processor without encumbering additional A/D/A steps.
Make sure the 550 does bass management & time delay on the multi-analog out. - The B&K's DVD-A mode bypasses it's processing.
But yes the digital will still be active, But you may need to set the "priority" output in the menu of the sony between the two to get the best performance.... pretty quick & easy.
I agree that the B&K will do a better job on any of the non- Blu Ray audio tracks.
Use co-ax digital over toslink if you can.
I'd get the Oppo player.- Or the new Sony 1000es player

I am a bit confused? I thought there were only 2 ways of getting DTS-HD to a receiver...HDMI and multichannel RCA cables??
You say you are hooking it up with a digital cable? So you can use a 75 ohm rca cable (digital) OR Toslink?
And if this is the case and true, why would you use digital RCA over toslink?
Or am I totally misunderstand your post. Are you using multichannel inputs AND IN ADDITION the digital cable for regular DTS (not DTS-HD)
