I got several issues of POLTERGEIST II, the original LP, the Varèse Deluxe, and the Kritzerland, so I feel quite set and never felt the need to pick up the Intrada (hey, I am cutting down on buying the same stuff over and over again.
)In any case, I never minded the (intense/dry) sound of the Varèse Deluxe to begin with, the Kritzerland has more air around the music and sounds more natural, so if I can keep only one of the two, it would be that one. Seems the dynamic range is bigger too, though I have not compared them 1:1 next to each other. I just prefer to put on a recording and listen to it and enjoy it. I got the Kritzerland comparatively late (after the Intrada already came out), but ever since I don't feel like picking up another copy of that score; I don't see what could be improved?
In any case, nevertheless, this is one great score and I think it is excellent that Intrada keeps in in circulation. Definitely a must buy if you don't have it yet.
