What does Jitter sound like?


I keep hearing the term jitter used to describe a kind of distortion that is especially problematic with CD Players.

What does Jitter sound like?
How can I identify it?

Shadorne, I suggest speaking with Kyle at Reference Audio Mods 951-780-2869 about a Superclock for one of your devices. The SC4 retails for $300 and there are probably cheaper used or old-stock SC3s. I have no experience with budget players, but reportedly he has had decent results with Oppo and others under $500.
Shadorne, I like where you're going with this. I think your results would make a very interesting read, and I whole-heartedly support the experiment! I think a good A/B switching with zero lag would be the best way to hear jitter and describe exactly what it does to the sound, other than "de-vinylize" it.

I can't do pefectly zero lag as the DSP amp takes two seconds to switch some pretty clunky relays - but this is close enough. I also would need to run it through my DSP amp as this has a multitude of inputs (toslink or SPDIF) and precise volume level matching capability. If the improvement cannot be heard through this DSP with AKM AK4382 192Khz/24 bit DAC's and a Crystal CS3310 analog attenuator and Burr Brown op amps then it is probably not worth the trouble as I would also need to upgrade this amp which is probably several thousand.

If I need to go to completely separate signal paths then it negates the possibility of A/B ing properly without moving and while seated at the listening position (with a remote in hand). If this were the case, then I am not really sure I could give up the convenience of the DSP unless the difference was truly impressive...
Having samples with jitter to compare would be meaningless unless the amount of jitter is quantified. Adding jitter to the point of making it an order of magnitude higher (nano seconds) than most decent players would not prove anything to me. Can anyone demonstrate that music through a cdp with around 300-400 ps of jitter as tested by stereophile would somehow gain astonishing resoluton by decreasing the jitter to say 100 ps as claimed by lessloss and the like? Does jitter get increasingly irrelevant as the sampling frequency is increased in the same player with a cheap clock, switching power supply and all?
