So, basically, I want something like this Mixamp. Is there any product out there like Mixamp that also has a optical OUT port? So I can run an optical cord from the console to the mixamp (where my headphones will reside) and also run another optical cord from the OUT port on the "Mixamp" like product to my receiver thus not breaking anything I have going on now?
Why not use a powered optical splitter?
A DSS (version 1) will get you console surround sound for cheap:
That's actually a binaural recording, not Dolby Headphone.
