All that formula shows is that more gain helps when noise is introduced after the amp, but does nothing if it's introduced before.
But you're absolutely right - for the question at hand it makes more sense to ask what happens when the output level is fixed. In that case gain and attentuation would cancel entirely unless there is some noise introduced between the attentuator and the amp - and if so more attentuation (and more gain) will make it worse (which is exactly what you said above). Sorry for confusing the issue. If I recall correctly distortion versus gain for an amp is also typically pretty flat if the power is held fixed - meaning this change is likely to have very little effect. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=34140 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
