Coax vs Optical: Does it really Matter?
Thought you might be interested or have a thought on this…
Many discussions about Optical vs Coax debate the advantages of one over the other. In looking for information about this I found this quantitative analysis.
The Well-Tempered Computer (thewelltemperedcomputer.com)
It mentioned in their analysis (on one device) that Optical is 7 times worse in jitter than Coax by their measurement. Wow I thought, that is significant. Then I looked at the scale of the problem. I’m an engineer by training…
In the audible range, the optical jitter is 1 nanosecond. Up at 1.3 Mhz it is 2 nanoseconds. Consider this: The latest research finds that Humans can percieve shifts in sound arrivals of only about ½ millisecond…

That makes the spdif optical jitter about
½ to ¼ million times smaller than our ability to hear the potential time variance.
