I feel that the audio for the OT should be based on the Laserdisc mixes, which have far more dynamic range than the Disney+/SE DVD/Blu-Ray mixes despite being stereo.
Don’t the Laserdisc versions gradually speed up over the course of the movie, though?
Only some Pan & Scan versions of Star Wars & Empire are sped up. All LDs of Jedi, The Pan & Scan CAV editions of Star Wars & Empire and all letterboxed versions of the trilogy are proper NTSC speed.
