Can you elaborate more on this 'feedback' jitter?

I have been experiencing a very weird problem with many CDP, DVD and SACD players. All the 50 or more players that I have tried will sound different depending on how the track is selected. Lately I am beginning to suspect that the jitter I hear is inherent in the discs itself due to the subcode data that are encoded alongside the audio data. Stereophile article by Harley briefly mentioned this.

Even the much touted memory buffer and reclocking technique employed in the Pionner VSX-A10i's IEEE 1394 receiver has failed to eliminate this problem.

See my prevous posts on this subject:

One problem is that many enginners and reviewers still have not been fully exposed to this problem. Those that might have, may lack the enginnering and financial resources to address this problem as it is an intrinsic problem with the whole optical disc retrival system itself. I have been told by a trusted source that the Ed Meitner new DAC has been able to solve this problem quite successfully. Ole Lund Christensen has also promised to address this problem in his upcoming SACD player.
