Sonance...I posted your response in another forum and Tonycdk replied in the following manner;
"Having a correct bit stream is not the problem . Almost all
players derive the correct bit stream (except for read errors that
may occur from really bad CDs).
Accurate digital reproduction requires that the original sampling
of the analog waveform from the microphone occurs at exactly
equal time increments, and then is converted back from digital at
exactly equal timing increments. If there is any slight variation in
the timing, either in the recording process or the reproduction
process (the two are independent of each other) the reproduced
waveform will not be exactly the same as the original.
It is basically more or less impossible to build hardware to
provide absolutely perfect timing. The slight scatter in the actual
length of the timing ( it is usually in the hundreds of pico second
range) results in what we call "jitter" and a slightly imperfect
waveform reproduction.
In any digital recording there is absolutely nothing we can do
about 'jitter' introduced by timing spread in the recording
equipment. This effect is encoded on the recording and can not
be removed. Fortunately most recording gear seems to be
reasonably good these days - although that may not be the case
for some early digital recordings.
Mostly, what we hear as 'jitter' results from the accuracy of the
timing in our gear. Having a perfect bit stream does not affect
the timing. This is why we put so much emphasis on accurate
clocking of the data stream - for example, why so many of us use
the Big Ben for re-clocking.
The short answer to your question is that having an accurate bit
stream is good, but is unrelated to the jitter issue."
This is why reclocking the signal pertains to the squeezebox even though the data stream originates from a hard drive!!!
