I’m not nearly done with the comparison–it seems to match the 83 stereo mix very well, but here’s an “I can’t tell!” example:
At around 22:38, while Bib Fortuna is delivering his “No bargain” line to Luke, and a little afterward as well, the 83 and 93 mixes both have the clinking sounds of chains. ROTP? Nothing, just dialogue. The reason I’m not sure is that I’m wondering if it’s possible the sounds are so high pitched that they are effectively trimmed out by either the EQ or the limits of the physical media. I’ll listen around for proof of this, but I don’t have a strong enough audio background to say this is so.
So it’s a cautious maybe, that it’s maybe a unique mix. No new dialogue or more major SFX differences so far, and I’m not done yet.
Would love confirmation from another listener.
