I actually sold my OPPO once I bought the Sony as it was then basically redundant.
Video is by HDMI direct to tv.
Audio is by spdif direct into the DAC of my Ayre EX8.
However if you do not have a separate dac you maybe better off as suggested just keeping the 105 for its DAC or.....
Sell both oppos and buy a cheap but capable DAC to run the Sony into and then into Marantz.
Just some food for thought.
