I think for one thing listening back at max volume actually will colour what
you're hearing far too much. You end up hearing the impact of the sound rather
than the subtleties. This goes for all kinds of listening situations of course.
I'd also ask whether recording at full gain will actually have an effect other
than the obvious.
