I tend to agree, however I continue to read about SB users utilizing the Pace-Car re-clocker in conjunction with very high quality modern external DACs. Why would this be necessary unless the external DAC isnt effective at reducing the jitter it is being fed? Obviously marketing comes into play but whos marketing the re-clockers, or the DAC manufacturers? I realize too, that there is some real science at play here. According to the designer, my external DAC is measured at less than 1ps jitter (0.005% @ 10 kHz; 0.0038 @14 kHz; 0.002% @20 kHz); but what do these low numbers really mean? Does this mean that the DAC is reducing the jitter from the transport down to these very low specs? If so, I cant see the need for a re-clocking device (unless 0.005% jitter is audible). However, there appears to be some science (and marketing) behind the concept that a re-clocker can significantly improve jitter in devices like the SB3/Duet even when these devices are used in conjunction with external DACs. Can someone help me understand this maybe sort through the science/marketing? -- timequest ------------------------------------------------------------------------ timequest's Profile: http://forums.slimdevices.com/member.php?userid=25640 View this thread: http://forums.slimdevices.com/showthread.php?t=63796
