[Help] Best mix for Aliens (1986)?

[listentomepowell]

Based on my limited listening and analysis, the TrueHD+Atmos track on the UHD-BD appears to be a new mix with some (slight) noise reduction. Some FX are removed like the door ramp closing hydraulic sound ~01:23:55. The accompanying AC3 "core" track however sounds suspiciously similar to the older DTS 5.1 mix. The 2.0 track on the UHD sounds exactly like the AC3 track and is most likley just a downmix of that track or the master that was used for it. The 2.0 and AC3 5.1 tracks have the heavy dither/tape hiss noise in the upper frequencies just like the DTS 5.1 mix and not like the TrueHD track. So... Disney/Fox did a new mix as an Atmos track and gave us the older mix as an AC3 track and a stereo track. I may be wrong here and all I wanted to do was point people in the right direction.

What about the Dolby Digital 4.1? It's on the Blu-ray and on the UHD disaster. With that kind of channel layout, it should be the genuine 70mm 6-track mix. They didn't even give it to us in a lossless format on the UHD unlike what they did Alien.

The BD 4.1 is missing the 'click' sound when Ripley presses the button to open Newt's hyper-sleep pod at the very end of the movie. It's present on all other mixes including the 35mm optical. It's possible that this sound wasn't present in the original 70mm 6-track mix or (more likely) that the BD track was subjected to some heavy-handed click removal resulting in some lost fx.

I've never found an audio track that I'm completely happy with for this movie and I'm pretty sure I have them all.

About the SE version, does the LD have the best audio?
