I should add that if there is no clock dependency in audio domain then how can we talk about jitter?
I can also add that I stopped paying any attention to cabling in general a long time ago.
It is true cables can sound dramatically different but only when intentionally constructed to introduce colorations or when used incorrectly in applications they were not designed for. When you compare cables that have proper capacitance, inductivity, insulation and construction for given purpose then you will struggle to hear differences regardless of their cost. Then you realize that it becomes much more effective to spend money on something that matters and brings improvements in transparency.
Almost anything can make an audible difference, but sounding different does not mean being more transparent. That is why I have been stuck with the same speakers and amplification for nearly a decade, every now and then I start looking at possible upgrades but I simply cannot find a component that would clearly bring a more transparent sound. There have been no fundamental improvements. Active speakers using DSP are very promising but nearly all are built to a price point with serious compromises that ruin the potential. For these reasons I have been stuck with Bryston amplification, I had nearly everything from Bryston lineup, up to 28B (not inclusive) and could not find something else that would be more satisfying. I am not saying it is perfect amplification and performs universally well no matter what kind of load it has to drive, I just happen to like what I hear. And based on my experience I decided to purchase blindly BR-20, it seems nearly everything in this product was done the way it should be, the potential for transparency is big. I have very high expectations; hope it will not be disappointing performer when it finally arrives
