Yes, but the chief server side tweaker is clearly quite mad, and has absolutely no way of knowing whether his dac is jitter insensitive or not. I would suggest that it isn't as insensitive as he thinks!. Clearly I don't buy into packet timing as a cause of output SPDIF timing jitter either, and also don't think that there is much that can be done to isolate the effect of the arm processor being active on the SPDIF clock. Better to concentrate on isolating the effect of Jitter than trying to eliminate it, but as you say, any fule know that. The problem with the vast majority of the nonsense in this thread is pointless conjecture looking at the hypothetical causes of wholly subjective experiences with no underpinning at all. Just look at the fact that this thread is now 165 pages long, and until recently nobody had bothered to check whether CPU utilisation was, in fact, higher or lower when playing flacs or wavs from the server!. Jeff - My flacs are level 5, so no idea if level 8 has a different effect. I think the coding process is asymmetric, so maybe level 8 doesn't take much longer to decode than level 5. The file size differences I have noticed are minimal between them. And yes, this does seem to fly in the face of Klaus's rationale for the purported subjective improvements. My view is that I haven't noticed any significant audible differences, at least not on the scale noticed by some, but am paranoid/tweaky enough to be using them anyway!.
