There is a test which can measure the audio effects of very small amounts of jitter, its actually quite simple: play a 15KHz sine wave, run it through a 24 bit ADC and run a very high resolution FFT. Someone did the math which shows that you should be able to see jitter differences in the 5ps range with this test. There is one drawback, the jitter of the ADC has to be significantly lower than the jitter of the tested system. The best ADC I have right now has about 50ps jitter which makes it unusable for this test. I have one which would be fairly easy to add some very low jitter clocks to but that will take some time and money, neither of which I have right now so its going to be a while before I could do such a test.
