Those were very credible, intelligent articles about jitter- thanks. I see that all digital source chains have the capability of generating a sonic signature based on the way they manage jitter. Quantative data regarding jitter however appears not to be standardized, not well correlated to audible effects, and is not made available to consumers of hi-fi gear. The arguments hence all seem a bit fuzzy.

The good news for computer audio is that there are "low-jitter USB interfaces available now that compete with the best CD playback devices," according to Mr. Nugent. The upshot is we're stuck with a certain amount of jitter coming from USB sources. The effects of that jitter can be managed well enough to be inaudible (or at least tolerable vs CD's) on all systems except those with the most extreme resolving-power. That may be a good enough answer (until the next playback system comes of age).

I retired my heavily modded (Superclock and other mods) Transport years ago. The jitter from some Computer Audio using USB is lower. These are my white-papers BTW.

  How do you judge what is better?

    Mostly by using the tool that is used in the end-product, the human ear.
    
    I know your game. You are trying to discredit me for not using 100% measurements to gauge quality. Well it doesn't work. It doesnt work with amplifiers or CD players or digital audio either. I trust my ears. They have not failed me yet. It's not by chance that my room at RMAF gets best of show.
