Hey Theo, As far as processor pass thru on the Luxman...the Luxman manual mentions it being able to drive the front left & right speakers and still be able to listen to CDs & LPs through the Luxman. This can be done by connecting Rotel outputs to MAIN IN of the Luxman. The Luxman has a Separate switch which disengages its preamp. Is this a sort of "pass thru"? As for the Oppo, it does have a stereo analog audio connection. If I understand correctly, this connection isn't affected by other settings in the audio processing set up menu of the Oppo. I'm unsure if I'f I can use the Oppo as 5.1, and stereo when desired. To answer your last question, I hope to use the Luxman to drive the front 803s for HT & 2 channel. Thank you.
