I agree with Tom, broadly. Get the playback curve right in the analogue
domain before you start messing about with it. The only way to do DSP
right is where you can process and control in real time. Few softwares
do this properly, and one is head and shoulders above the rest, in my
view. If you can't do good DSP, it's better to leave alone, or at the
very least keep an unprocessed copy. For mastering purposes, of course,
the ear must be the final arbiter - all the rest is to ensure you start
from a sound platform. Was it Schumann who said "if it sounds right, it
is right"?
