Rotarius....THANK YOU!!
Over-clocked under-flow buffer bits blah blah blah blah...
The question was WHAT DOES JITTER SOUND LIKE, and the conversation degraded into a brain battle of engineers. If small amounts of jitter affected sound like small amounts of other distortions, then the above question would have a real answer such as could be given to the following questions:
What does mistracking sound like?
What does a ground-loop sound like?
These are things we can identify. Instead, we're arguing about whether we can even hear it or not, and the final answer (assuming it's something we actually can hear) seems to be "it sounds like less clarity." With an answer like that, you might as well be saying "ummmm... it just sounds worser."
