So I've read the articles about this release, and it appears to me (unless I'm reading them wrong) that this is not taken from the 24-track 2" analog tape, but rather from a "rough stereo mix" on 1/2" analog tape? Downmixed while it was being recorded live. So that this mix may not be as good as what was originally released, as there isn't much that one can do to adjust a recording that is already stereo to begin with?
Of course the frequency response will be better, but the mix itself?
Or maybe the "rough stereo mix" was pretty much the same as what was used for the final mix...
