Just asking because i don’t have them myself and i do have the laserdiscs, only my player can only output the 2 channel digital audio as i don’t have an rf ac3 out.
I remember they sounded like very good mixes in the theater, though i probably saw them in some other audio format than dolby, but not the rare dts presentation that was on the 70mm prints.
Just wanted to hear them again as an audio engineer Steve Hoffman said they sounded like garbage in comparison to the analog 70mm presentation in 1977, which i cannot fathom being true as they had lots of limiting done on the soundtracks in those days, no digital mixing studios or digital audio, when they set about to do the redo in 96 they found the original track masters that the 70mm was derived from where there was almost no generation loss.
