Probably I'm misunderstanding the issue here, but I'm not sure what you would measure. The earlier response from Robin Bowes makes some sense to me - I suppose when the DAC receives the signal from the squeezebox, it might use the (say) rising edges of the signal as a clock. If the PSU induced some noise in the signal, like rounding off the edges or just adding junk, maybe that can make the DAC clock "tick" a bit early or late, and therefore cause it to change its analogue output level at not quite the correct time (i.e. induce jitter). Is that the general idea, Robin? But that seems to me to be a combination of the characteristics of the digital output of the sbox and of the DAC itself, so maybe any measurement you did on the sbox output alone might not mean much? -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=21556 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
