I have a detailed knowledge of the various sound mixes for Star Wars, but I am less familiar with Empire and Jedi. I want to have an accurate theatrical sound mix and I’m wondering if there were any changes that I have not caught between the initial theatrical and home video releases and the 1985 release and the 1993 Definitive Edition/Faces/GOUT releases. At the moment I am unaware of any changes to the stereo/surround sound mix from the original 35 mm theatrical version to the 1993 version. But I wanted to check with the community before I continue with that assumption. I am aware that there are some sound quality differences between the versions (dynamics, stereo field width, etc.) but I am looking for actual edits like Star Wars has (the appearing and disappearing Threepio tractor beam line, the many differences between the original mono and stereo versions and the partial inclusion of some of the mono variations in the 1993 version). I understand Empire might have had a unique mono mix, but I have never come across it. I just want to be complete if those two movies any any similar edits that I might have missed. Especially since I am mostly familiar with the 1985 and 1993 versions.
