Confirms with packet analysis that the whole file is transmitted to the Phantom

-----------
So, the amount of jitter you alter from the optical cable is down to the jitter of the optical receiver.  The dialog then transports the LPCM data to the phantom in chunks as if it is a digital file.  This is in contrast to a traditional transport/DAC.

Therefore, the only jitter is what's introduced inside the physical phantom itself and the only modification that exists would be the power cable itself...
