Unfortunately, this doesn't answer any of my questions. One is, how much of a difference thus the step up to using a Transporter's AES/EBU output and word clock synchronisation?
Note I'm an analytical thinker, thus would prefer something audible to be backed by data. But technical analysis, however sound, can never prove equipment sounds good. Jitter is a measurable phenomenon proven to be detrimental to the sound quality, thus its absence assumed to be beneficial. It's basically the one factor we know so far. Given how different CD-transports sound regardless of how well or badly they measure, my expectation is that someone is going to find other, hopefully measurable and reproducible factors. In other words, I'm not too obsessed with jitter measurements, especially given jitter isn't all that easy to measure right in the first place. I remember reading a report a few years ago, by the way, in which the jitter of some CD-transport was identical (or then below their Hewlett Packard, if not even Brüel & Kjaer equipment's measuring capacity) measured from this same transport's four different digital outputs (S/PDIF coaxial, Toslink, AES/EBU - the fourth an AT&T optical or a BNC coaxial, I'm not sure anymore) - "inexplicably" the blind tests that magazine showed that none sounded identical to the other three. I cannot say I was surprised when I read it: we tend to hope for simple answers to difficult questions, it's only human, but more often than not, the answers aren't simple.
