We're talking 24 bit here, not 16. Like I said, nobody has ever been able to demonstrate that moving a fader in a DAW has any detrimental effect whatever.
If it is a problem, it should be easy to demonstrate. Run a file through a bunch of digital faders, move them up and down, then compensate at the end. See if there's a difference. There isn't.
It's one less thing to worry about.
