1989 Criterion LaserDisc [CC1108L]: Excellent sound. Female voices sound much more life-like than they do in every later release.
~1991 UAV VHS: This is a bootleg with a linear track. It sounds awful.
1998 Criterion DVD: More noise reduction than the LaserDisc, making this sound veiled and boxy.
2007 Criterion DVD: Similar to the first Criterion DVD but not identical.
2011 Criterion Blu-ray: Even more noise reduction than the previous DVDs, and some additional bass reduction too.
2014 Great Movies Blu-ray: This German bootleg* (see comment below) is identical to the Criterion.
