It turns out that jitter does not do what one thinks it does.   On the first listen one may hear that the jittered source is warmer, but with a little ear education, the sound is recognized as muddy.  In mixing the use of eq to brighten a sound can increase the level of the jitter artifacts.  There will always be some one with a better playback system where the jitter artifacts  will become more apparent.  There are many things in circuit design that cause jitter and some things that can be done in studio wiring that can help reduce the problems.  Taking the time to learn will result in better recorded audio.

All files are phase canceled with the B file, which is the reference.  B is the clean, most open file.
The B reference file has the lowest jitter, 13pS  rms measured with the Stanford SR1, with the low jitter option

The phase canceled files have added gain to make them easier to hear.  Very low levels of jitter are audible.  Jitter destroys; image, openness, transits, size, smoothness, and can be harsh.)

The gain of the phase canceled files is as follows:

B-A 72 db of gain
B-C 36 db of gain
B-D 36 db of gain
B-E 24 db of gain

The jitter is filtered noise with different center frequencies, 3 are bandpass filtered.  The 10Hz noise is different it is low pass filtered.  Different types of jitter have different audible effects.

The jitter levels have been pushed to very high levels to help ear education.
