Probably the 20th Century Records vinyl of Star Wars. And the first issue RSO Empire Strikes Back.

I’ve heard various things over the years that either the Japanese or UK pressings were better but all I have is the US release.

If it has to be a release of the movies it is the 1995 THX Boxed set, with the making of trilogy on Laserdisc. Good picture for laserdisc, great audio. And I don’t mind the Japanese subtitles, though not having the Huttese dialog is a complaint. I do have the 1997 and 2000 sets but I haven’t watched them. Other than to sample the quality of the audio which was excellent. But George can keep Greedo shooting first.
