Right, early MoFi was a bit of a contradiction in that Ricker applied that rock V curve to everything, so it was far from accurate. I think he was mostly interested in the raw tapes to get more dynamics and a flatter sound so he could impose his own curve on top. Post acquisition, they really are a different outfit with different engineers (although some were trained by Stan) and a new mastering chain and flat transfer philosophy. IIRC, they even stopped half-speed mastering in recent years which was Ricker's signature move. The enduring legacy of early MoFi to the audiophile world was that idea of returning to the original tapes whenever possible. That was copied by all the other following audiophile labels because it was really a unique proposition in the industry.

this post by Hoffman out. Ignoring that Hoffman does like to spin some yarns, and that this is an extreme example, this is the exact type of thing I'm talking about. His CD master, and Kevin Gray's MCA heavy vinyl issue from the 90s use the original tapes. Of course some people may still prefer the sound of the TML cuts from any iteration as all of this is super subjective, but in a best case scenario his version and Kevin's version should be closer to the sound heard by The Who in the studio. This is say what is better and what someone would prefer. In fact based on this tale it seemed the band themselves were quite happy with the prospect of TML doing their thing to the masters, for whatever that is worth. There were quite a few other documented examples of studios that cut from cutting master tapes only, like Bell Sound, and Capitol in the 60s, and more.
The whole OG vs AAA reissue thing is really becoming quite a stupid debate IMO, especially in the jazz community as you mention. In my view there's no reason to be sectarian, as I've heard good and bad OG pressings and good and bad reissues. I just wanted to point out that there are plenty of advantages to AAA master-tape sourced reissues, and I've heard some that kill my earlier copies to my ears (Rumors, Blue, and Electric Warrior by Kevin Gray).
