Isn't someone adding digital audio output to the Receiver hardware? I think the approach is to replace the power speaker/amp daughter board with a board that provides SP/DIF out? The intent is to provide simple stereo (two channels only) output in the SP/DIF format.

It was attempted, using the same hardware that is used to add sp/dif out to the empeg/Rio Car. If I remember correctly he never got it to work on the Receiver.
