Perhaps my understanding is faulty; I'd always thought processing should be
done at a higher resolution if possible to minimize adverse effects on the
signal and preserve as much resolution as possible. Applying certain effects
to 16 bit audio if editing in 16 bit resolution could result in loss of
resolution could it not?

OK...so am I understanding correctly that you are transferring through 
your converter into your computer at 16bit, but then importing it into 
ProTools for 24bit?

If this is the case, you're not "enhancing" the sound quality, but just 
using some kind of algorithm(s) in order to get a more complex file - 
information that was added, by the way, and has nothing to do with the 
original.
