Since my high freq hearing is pretty knackered I cannot from ear come up with a good candidate. But I'll try the jitter test for a laugh !
Well with my laptop and Senn HD535 I could not tel j2 apart from the original but my hearing is not great !
I woulda *sworn* I hit 'Submit' for this, but maybe not, apologies if re-post.
The following is a foobar2000 ABX of Nick Charles' Range.wav file, with jitter added by stv014, thank you to both for the test files. Planned set of 15, but you'll see I chickened out at 14.

Not much to listen for here, especially in such a busy and trebly mix. Too sizzling for my taste, I'd want a do-over if a recording studio handed this to me as a client.
If you want to give it a shot, here's how I got to it: find the shortest, sharpest, loudest transient you can. No cymbals, the 'short' is important. I used the second-to-last snare hit in the clip. Use the 'A' version to burn that sound into your mental ear, then compare directly to X and to Y, either one first. To my ears, the jittered version was just slightly blurred.
Nick, if y'all want to pursue this, I'd be thinking about something that might expose graininess and breakup due to jitter on sustained notes, instead of hunting down transients. Classical piano, slow, with a held chord somewhere? I don't have any software to deliberately jitter with, so I'd need to pick that up somewhere.
