It's actually quite difficult to understand exactly what your test involves, but looking at your linked page, I get the impression that you are proposing this:
1. Take a file with a very low level signal (eg. -80dB). 2. Play it without digital attenuation, and increase the analogue gain until you can hear it. 3. Now apply some digital attenuation and increase the analogue gain to compensate (so the overall level is the same). 4. There will be an audible difference. Is that what you're saying? If it is, then my response is: "hey, no sh*t, Sherlock! Now tell us something we don't already understand". And then try and justify how this extremely unrealistic scenario relates in any way to the normal listening experience. Presumably you tried this test with a signal at normal levels (ie. not artificially low) and failed to hear a difference? What does that tell you about the real world? mswlogo;538748 Wrote: > Your ears, system, room, amp, dac etc. have a total fixed dynamic range > and by using digital attenuation you are sliding the music out of that > range. And when you use analogue attenuation you are sliding the music out of that range. -- 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 [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
