The benefit of this test is that you can listen to the difference, with your own ears. If the difference by itself is not audible at all, I'm perfectly happy concluding that it's not audible when masked by a much, much louder musical signal. For that not to be true would require hearing to be extraordinarily non-linear, in a way that there is no hint of at all in any psychoacoustic or hearing research I've ever heard of. > Your testing can show that cables, etc. can sound the same on your DAC. > But you have not shown that your DAC does this without adding any > colouration of its own.

Just record their outputs and difference them. The results would be interesting, and I think Phil could do that easily - e.g. he could compare the SB3 DAC to his main DAC. I'm pretty sure that will detect at least the display noise which seems to be present in the SB3 analogue output. Whether it finds any signal related component would be interesting to see. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=60041 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
