Now we are getting into the new area of streaming data, and SPDIF is NOT the way to go, as it is subject to jitter and timing issues. The error free way to do this is over CAT5 and LAN connection, where the data is fed into a buffer into the DAC. The the PC/NAS drive can out perform even the best Transport. I now use this method myself, NAS drive into Linn Akurate streaming DAC.
