"can't you use a single RCA digital or Toslink for 5.1?"
I believe these are considered inferior connection paths compared to full set of 5.1 analogs or HDMI, even for downmixed output.
"I thought the Oppo 95 was aimed at those who preferred analog output for music, and that only its analog differs from the $500 BDP 93."
It's very much more than that. You may wish to check currently available reviews and intercomparisons.
That said, the BDP-93 sure looks like a good value, esp with used prices headed south.
