I agree to a certain extent.
Devil's advocate.
Did the first engineer in effect change the sound too?
It's kind of a question of who stays truest to the tape and that's a pandora's box situational to every release.
The TT setup was killer at the end.
Also another vote for the DL-103R carts. They are fantastic.
OK - devil's advocate back!
The original mastering engineer had the guidance of the producer and in many cases approval of the artist.
In that context, it's not about staying true to the tape - in most cases, you don't really want that. The tape presents the master mix to reel to reel, presumably the mix and consequent adjustments the producer and artist worked on. Then, in the first transfer to lacquer, the mastering engineer makes adjustments to make it sound as good as possible on the medium - vinyl, in this case, and that gets approved by the producer and possibly artist.
So - of course, the first engineer changed the sound. But the difference is that it was done to suit the producer and artist intent and preferences.
So, IMO, anything after that cannot be definitive, unless approved by the artist - and even then, later choices may not always be the best without the producer's guiding ears.
But now comes the problem at hand. First, we have better mastering technology today, and we no longer need to consider cheap turntables in mastering. So the notion of being faithful to the original is out the window. Second, Teo Macero, George Martin, Alfred Lion etc. etc. are no longer here, nor are Miles, Lennon, Coltrane and so many others. So the notion of producer and artist approved is off the table.
Third, we have the condundrum that we can do more with that master tape today. We aren't doing a mass produced product, and we can get more from the tape and make better mastering choices. But that automatically means that it is the mastering engineer's interpretation - and that will always be subjective. That's why another engineer can come along, make new, different choices and - like magic - we have a new, best it has ever sounded version. But in fact, it is just different subjective choices.
No one is true to the tape, in the sense of making a straight, faithful transfer to another medium. It is always an interpretation.
I look at it like this. We have hundreds of years of classical scores, on written paper. Those are the masters and the artist intentions are very clearly marked all over them. That is definitive. But that does not mean there is not room for interpretation, or even choices that suit modern tastes and performing practices subjectively better. But that means that there is no, one, single definitive performance, even though for many decades, record labels have made the claim that one or another are.
