That's never been said here.
In fact its the opposite. Otherwise we wouldn't need the z at all would we?
The z processes everything on the soundcore3d chip and then sends the digital PCM stream to either the onboard DAC for conversion to analogue and/or sends it out through optical to an external DAC.
So basically the stream is the exact same as the one going to the onboard DAC, it just gets split into another duplicate stream to go through optical. This way its simple, efficient and does not require any extra calculations on the sound processor. But this second duplicate stream only gets sent to optical port if the "play stereo mix to digital output" option is enabled in the control panel of the Z.
