I've never measured any audible jitter. Jitter is a joke of the audio
equipment industry.
A simple test case is to record 18 kHz on a CD and play back this via
headphone (for speakers it is dangerous).
You hear:
* Modulation noise of the amplifier (hum, noise)
* Bit errors (clicks)
Every amplifier I've tested are so worse that you haven't any chance to
hear the effects of jitter.
