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.
