Stereophile:
Cd, Jtter, Errors & Magic

Conclusion: From my measurements, it is apparent that none of these CD tweaks ha I am convinced that undiscovered optical phenomena in CD playback affect sound quality.
Only by combining critical listening with the scientific method can these mysteries be solved.
Although I had wanted to find measurable differences with the tweaks, the experiments at least ruled out data errors and jitter as the cause of audible differences.
More significantly, however, the jitter measurements led to the hypothesis that the conditions under which CDs are made have audible effects on playback quality.
This idea has profound ramifications, warranting a full investigation to reveal its merit. This is an exciting time to witness digital audio's evolution.
We are on the verge of identifying and understanding the subtle mechanisms that affect the digital musical experience.
We may one day look back on today's digital audio quality the way we now look at a 1950s-era black-and-white television, considered a miracle of technology in its day.
Only by realizing digital audio's flaws can real improvement be made.
