RE: Got Jitter?

Posted by knewton on April 7, 2017 at 06:11:16:
The benefit of extreme jitter reduction seems like many other subjects in audio - highly disputed. I've reached no conclusion regarding continued jitter reduction aside from the general notion that if something is undesired in high quantities, then continually reducing it cannot be a bad thing. However, just as with harmonic distortion reduction, how low is low enough to be imperceptible? Is zero harmonic distortion really required? Are femtosecond levels of jitter really required? Some of the most highly regarded DACs actually utilize little no audio band jitter reduction. Audio Note and Ypsilon come quickly to mind.

Part of the difficulty with DACs is that they contain so many interrelated functional mechanisms that it can be very difficult to assign a given subjective listening artifact correctly to a single objective mechanism. One sign that may be trying to do that is when we percieve further reduction in some already vanishly low error parameter as perceptible.
