Just for thought, check out this advice from Ian Shepherd from productionadvice.co.uk
"One of the things we like about analogue gear is the soft saturation distortion it can add when you push it hard. And plugins that emulate this effect do the same.
So if the whole mix is running up into the red on the channels, and you’re using some processing that works in this way, you may end up with much more saturation and distortion than you intended. Better to stay on the safe side and keep the levels lower to avoid this happening by mistake.
And that means running all the channels in the mix at a lower level, not just pulling back the master fader. 32-bit float will prevent clipping, but if all your channel faders are maxing out, their plugins could be quite heavily overcooked – and pulling the level back at the last minute won’t help with that."
