Don't hold your breath for measurements in the analogue domain that correlate to sonic improvement for devices that don't have gross audible differences. John Westlake has already shown measured differences in cleaning up the USB signal & tightening the USB packet timing. Amir, BE718 insist that DAC analogue output is the only place to do measurements & have shown higher amplitude 8KHz spikes (& their harmonics). This is exactly what is to be expected when the jitter of the USB frames & microframes is reduced. Microframe timing of 125uS gives rise to a frequency of 8KHz (& harmonics) when the logic gates in the USB receiver fire at this interval causing a ground noise spike or logic induced modulation (LIM) as it is known by. So we seem to have measurements of the effectiveness of the Regen ion the USB signal & further along the chain, on the DAC output.
Can this be directly correlated to audible differences? Obviously, not but how many subtle differences, can? I wouldn't be surprised if the next demand will be that we don't actually listen to the DAC output so the analogue signal should be measured further downstream - hell measurements should only be measured from the speaker as that is what we listen to, right? ------------------------------------------------------------------------ jkeny's Profile: http://forums.slimdevices.com/member.php?userid=35192 View this thread: http://forums.slimdevices.com/showthread.php?t=104340 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
