Did you just choose the 1981 release because it's "original" or did you not know this? Even analogue LD audio is occasionally better than DVD or Blu-ray audio because more modern formats are generally more likely to have audio that has been messed with ("restored") in ways that destroy the integrity of the original presentation. With mono, it's arguably slightly less of a problem if you use a compressed source (e.g. DVD) but that doesn't make much difference if the recording has been mucked about so badly that it sounds terrible.
Also, there is a project that exists to record and then decode (after the fact) the raw RF modulated information from a modified player, but I've never looked into it in any great depth in relation to audio specifically and I suspect it's more useful for video. For PCM it's largely pointless because you can get a bit perfect copy of that already if you configure your setup correctly, which there are guides on the forum for.
I was talking about using an (imaginary) LaserDisc drive connected to a PC to get the full uncompressed mono mix file. Sony apparently introduced a LaserDisc format that could store digital data back in 1984, but I doubt you could find a usuable drive today compatible with modern hardware; let alone how hard it might be to grab the audio file in question.
My video knowledge is far supperior than anything related to audio, so I was not aware that recording PCM through analog with a good / calibrated setup could be considered as a perfect transfer.
Traditionnally, mono mixes are rarely ever tinkered with, so I doubt you would get a better sounding version on newer LaserDisc. But I agree with you on stereo and 5.1; we can suspect every single DVD or Blu-ray releases to sound different.
But fear not, me buying a 1981 LaserDisc had nothing to do with it's mono mix. It's for the memorabilia more than anything else.
