I know m8 but unless things have changed a lot u can only hear one at a time...
In wavelab I can hear the final master in realtime passed thru eq, multicomp, comp, ultramax, stereo expander... I can go an change parameters n check which sounds sweetest... that's what I meant in the first place...
my bad I really didn't explain properly!!

PS - also u can record a preset of yer mastering chain with they're parameters and all... so u can go back and change stuff, or compare stuff.. etc...
