The noise floor of the programme material is vastly higher than the DAC's own noise floor (and the point where DAC linearity degrades). b). The listening environment will have a background noise level vastly higher than the DAC's. These two factors completely mask any benefit gained by operating the DAC in its most linear range. (Within reason, of course. As always, it is important to get the gain staging correct). Here's your fundamental problem: you are unable to distinguish perfectly valid theoretical issues from their real-world consequences. You have heard an improvement in sound quality where there is none. There's a very rational explanation for this: it's called expectation bias. mswlogo;543857 Wrote: > You are assuming a DAC is perfect, even at 20bits. It's not. I never said that. What I have been at pains to explain to you is that the imperfections of DACs operating in their non-linear ranges are beneath the threshold of audibility in a normal listening situation. The only way you were able to objectively demonstrate the degradation that happens when a DAC is operating in its non-linear range was to prepare an artificial sample and boost the analogue gain to insane levels. As I said in my very first response to you, "no sh*t, Sherlock!". This is hardly a surprise to anyone. It's simply an extreme example of what happens when the gain staging is wrong - very wrong in this case. -- cliveb Transporter -> ATC SCM100A ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=77725 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
