You appear to be making the classic mistake of assuming you need as much dynamic range when listening at low levels as you do when listening at high levels. You don't.
If you need 100dB of dynamic range when listening at a peak level of 100dB SPL, then you only need 90dB dynamic range when listening at a peak level of 90dB SPL. When you attenuate by 10dB to reduce the listening level that much, you can afford to lose 10dB of dynamic range. That's why it doesn't matter whether you do the attenuation by digital or analogue means. -- 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
