Since the purpose of the preamp setting is to apply a fixed amount of attenuation only at the DAC (and not the s/pdif), it is better to use the (free) hardware attenuator in the DAC than to spend CPU cycles doing an additional one in software. If it were supposed to apply to both outputs, then yes we would just use the one attenuator in software - in that case we would just apply a scaling factor to the existing volume control. Another reason for doing it in the DAC is that it made it easy to add the feature without increasing code complexity. BTW, I personally don't like the preamp setting but I added it because so many people wanted it. So I agree it's a bit odd and I'm not trying to defend it, just explaining how it works. -- seanadams ------------------------------------------------------------------------ seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=35642 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
