Yes they reduce SNR - but if the N is low enough anyway it won't get in the way of comparing the S when the S is boosted back to its pre-attenuated level - which is what ADM does. Yes they reduce dynamic range. But when ADM re-boosts the signal that isn't apparent - it seems to act like a rather good/very linear compander... The fact remains that what I'm seeing and hearing is a nice linear reduction in "volume" without any other deleterious (non-linear) effects - just like you would get with a very good analogue control. I can't see anything wrong with the methodology at the moment? -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
