Secondly, even if you do get the gain staging spot-on, no DAC or ADC is perfect, so you ought to expect a change in the least significant bits.
But no matter.... Phil Leigh;234683 Wrote: > Repeat with endless cables - analyze the results. > I'd expect to find that some cables changed the sound and some > didn't... If you left the gain staging unchanged between tests, then this will indeed measure any difference between the cables. And it wouldn't surprise me if there was some minor measurable difference in the resulting bits. (For example, cables with very slightly different resistances will deliver a marginally different voltage at the ADC inputs - effectively changing the gain-staging). But would those differences be audible? I suspect not. Your experiment is a way to measure a difference that might not be relevant. It's the other side of the coin to the argument that there may be important differences which we don't know how to measure. -- 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=38902 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
