Jitter is not audible.

For those of you that worry about jitter, don't, jitter is not audible until 30,000ps in a sighted and direct controlled test and 250,000ps in a blind test.

How so? If you do not agree with this paper on jitter please post up your own information. Not only do they discuss jitter in theory but they do a real life listening test, something that the high end is against.

Quote from the text linked above "Experiments were carried out in the listening booth or studio that each listener had offered. The examiner only brought there a personal computer with a digital audio interface and a mouse and each listener provided his or her favorite DAC, amplifiers and loudspeakers."

Knowing what we know about USB DACs and interfaces between portable computers and DACs, it's no wonder that jitter differences were masked by this inferior and highly variable interface methodology. Also these tests were done in 2005 when the quality of USB DACs was far inferior to today.

p.s. audiophile and high end audio always use real life listening test.

p.p.s. when are you going to spend time on something that you have interest in. It's clear that it's not hifi.
