Cut from the original analog half-inch tapes and mastered by Bernie Grundman (engineer of the original release), the studio recordings have been lovingly pressed on 180-gram heavyweight vinyl.
I don't think that seems that nebulous? When places say "cut from the original analogue", they mean it went from analogue to analogue right? There always seems to be a distinction between "cut from" and "mastered from original tapes". Mastered from always seems to imply a digital step was added in mastering while "cut from" always seems to imply they cut the lacquer straight from the tape.
But I think
@dhodo is right. There's no direct confirmation re: the 2015 cut outside of that press release while Storf clearly says this version is NOT AAA.
