Nah... That would throw out all of the other settings, and all of the sound fields would be off. Besides, my receiver comes with a mic and calibrates itself based on 6 minutes of test tones. It has proven to be MUCH more accurate than I could get by manual measurement.
Maybe on the re-re-re-re-re-release (all 6 episodes), they'll re-re-re-re-re-remaster the audio. =]
