understood. but what cliveb was saying is that in addition to the speed change you describe, the speed of the drive is also adjusted to stay in sync with the clock of DAC to keep the bit flow into the buffer at the same rate as it is clocked out for the DAC. it seems to me that trying to keep a mechanical drive in sync with a clock is not an easy thing. -- pvadbx ------------------------------------------------------------------------ pvadbx's Profile: http://forums.slimdevices.com/member.php?userid=5719 View this thread: http://forums.slimdevices.com/showthread.php?t=28621 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
