The press release also contains this:

“Mastered from the original analog master tapes, Mobile Fidelity will also make the original Thriller album available as a One-Step 180g 33RPM LP, pressed at RTI and strictly limited to 40,000 numbered copies plus an SACD hybrid.(One UltraDisc One-Step 180g 45RPM 2LP set of Polar will be published at a later date.)”

Unfortunately, as we all know, the major labels have often faked the meaning of “mastered from the original analog master tapes” into nonsense, so we’ll try to get some clarification on that and edit this post as soon as possible ! But to think this would be the first version of Mobile Fidelity that we know was do not mastered by Mobile Fidelity on its own lap, so there’s a good chance it came from a digital file. Yes, continue with that until we hear otherwise.
