Shout! Factory 4K Blu-ray

Twilight Time Blu-ray or MGM NTSC DVD for the original mono mix

• Shout! Factory 4K only has a stereo downmix (which sounds muffled, as do the surround tracks)

• Twilight Time Blu-ray has the mono track with seemingly the best fidelity, but its dynamic range has been heavily compressed

• MoC UK Blu-ray has a proper dynamics and good fidelity, but bizzarely, everything is repeated after a few miliseconds, rendering echoey and metallic

• MGM NTSC DVD has been denoised and has had a strong EQ applied and sounds muffled as a result, but it retains proper dynamics

• Koch Media DE BD had poor dynamics and wrong pitch

• Analog 1986 US LaserDisc sounds poor
  

Perhaps the digital JP LD would be better.

Kino Lorber 4K Blu-ray

Kino Lorber 4K Blu-ray has poor encode: Dolby Vision caps

DVD or LaserDisc for original mix Thanks to the magic of Dolby Stereo encoding the 2.0 mix actually has much better surround activity compared to the 5.1 mix, which feels flat and lifeless. The surround mix is also missing elements (eg @ 0:04:58 the zapping sound doesn't extend to the surrounds on the 5.1 track, same with the flickering sound @ 0:21:46, etc)
