Since they are not data correlated, the threshold of audibility will higher, than with data correlated artifacts. Of course, with any form of jitter, you don't actually hear the jitter itself. What you hear are its effects. Which are not something one can say with 100% certainty will sound a certain way, in any and all instances.
What you do hear is its absence, once it has been removed. The main problem with SPDIF is that it has such a high level of data correlated jitter problems, that in all likelihood, the problems folks like me can measure may not turn up in routine listening. Things are a bit more involved, when we are discussing products like the Duet and SB2/3. The clock shares the same chip as the SPDIF circuitry. (The Transporter may be different; haven't worked on any.) Noise from the common supply and ground pins can affect the clock. In addition, there is the intrinsic noise of the regulator. How much of this gets passed on? Can't say exactly, but my experience is "some". "Some" may be a trifling amount to one crowd, or a "huge difference" to others more prone to hyperbole. Having said all of that, my guess is that 99% of the folks here won't be able to tell a difference. So, they proclaim since they can't hear it, it doesn't exist. The remaining 1% will become hysterical, and claim the others are either deaf or have inferior systems. All I can say is "Yes, there is a measurable difference, so it is very likely in some systems, some listeners will notice a change." But the question you are really asking is more complex. How DACs deal with jitter, and how it will affect the sound is way beyond the scope of this thread. But let's say there are many factors which enter into that discussion that are overlooked by a lot of the folks who make them. Of course, they will disagree, which is their right. Won't negate what I am saying.
