Ian, all this is correct, but doesn't really address the point at issue which is whether the file type being transferred over the ethernet affects the input jitter to SB or ID40 (which obviously it doesn't because you can't even define jitter for asynchronous transfer whether it is under TCP or UDP - jitter doesn't exist till you have a synchronous - ie clocked - bitstream). TCP versus UDP can obviously affect dropped packets, buffer under-run etc on a dodgy network, but the effect of that is dropouts not degraded SQ. I have been careful throughout to point out that I am assuming sufficient processing power and bandwidth to avoid drop-outs, dropped packets, buffer under-run etc. AFAIK it's TCP except for MP3 BTW, so TCP for both PCM and FLAC.
