what is jitter supposed to sound like?

The Stereophile CD is a good idea. If you want a verbal description from someone who has battled it a bunch, I would say that it makes everything less distinct. It removes the fine details that create depth cues and the quick, high frequency transients that make percussive and plucked instruments sound real and exiting.

Sounds loke something that you have never heard before! If you could hear it, it would sound like a low level hiss.
More important, how would the recording sound without dither? How can one know, since dither is always used as standard.

Opps, I confused 'jitter' with 'dither'! Definitely not the same and of course my comments on 'dither' don't apply here for 'jitter'. My bad!
