I do have the OST for all three OT films on vinyl, and can definitely hear advantages (and disadvantages) of analog.
Are you talking about the music soundtracks or the “The Story of…” records?
Music – OST is original soundtrack (the commercial LP release of John Williams’ score).
Japanaese pressings of which are pretty good.
I do own all three ‘Story’ LPs, too, along with other movies’ story LPs like The Black Hole, Tron, etc. These all have marginal sonics.
