I think you misunderstood, I wasn't clear enough in my reply. I suggested the RCA to E9 combo over a Coaxial out to a converter. Definitely should not have said converter / E10. Strip off the E10, my bad.
Coaxial out has some trouble with bass and subwoofers, google that for a fun read. Stick with RCA to an authentic Amplifier, in my experience it works flawlessly for DVD players and sounds pretty darn good.
