Endian, I watched the CAV LaserDisc of Jurassic Park last night. Good old PCM Lt/Rt audio. And yes, I noticed the distortions on some lines of dialogue. I'm glad to find out I wasn't the only one.
Perhaps those distortions were inherent to the mix. Not a miscalculation in the transfer, but dialogue distortion right in the master. Strange. Also Jurassic Park is a very hot film. It's loud and never lets go. Even with its imperfections, I prefer the 1994 CAV LaserDisc audio to the 2013 IMAX audio for the 3D version.
Also, can you by any chance hook me up with the theatrical far field DTSHDMA of JP? I really want to listen to it right now.
