In Reply to: I thought he was talking about buffering the data in the DAC posted by SoftwireEngineer on January 17, 2008 at 10:51:09:
So, no, I'm not talking about buffering with something like S/PDIF, which several DACs currently implement (notably the Chord 64, which buffers up to 2 seconds of data, I believe),
