Thanks for taking the time to do this.

So... it seems that these papers are establishing some sort of
ball-park threshold of audibility for word clock jitter.

So here's the important question: when we see published specs for
jitter on a transport's SPDIF output, which is it: word or bit clock
jitter? Seems like it's crucial that we know the difference before we
can even start guessing at whether it's a respectable figure.

I realise that your personal interest is in reducing jitter on the
clocks inside DACs, but to the man in the street that's not really
important: he buys DAC X or DAC Y according to which sounds better.
Whether the improvement is down to better analogue circuitry, lower
internal jitter, or other factors (such as noise pickup from the
environment) is frankly of no consequence to him: he's in no position
to change it.
