This might even lead to ....Jitter! The most famous study of this was by Julian Dunn & Ian Dennis (Prism) and Doug Carson (DCA). They investigated apparent audible differences in numerically identical CDs. Their paper was called "The Numerically-Identical CD Mystery: A Study in Perception versus Measurement", but I'm afraid I don't have a URL for it. (If anyone wants a copy send me a PM).
Anyhow, the main conclusion was that the impact of servo activity is NOT on jitter, but that it caused amplitude modulation of the analogue outputs. (No effects were found in two-box players). -- cliveb Transporter -> ATC SCM100A ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=39093 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
