As to what the "correct" sound stage is, I agree that to some extent the decisions of the mixer is relevant for a lot of music. But I think it's much less arbitrary for a classical music concert for example recorded in a particular venue. There is still some arbitrariness as the microphones would usually be placed somewhere that doesn't precisely replicate any given seat in the auditorium.
I'm surprised by what I think is the lack of good information on this. I wonder for example, whether an expert classical music listener Would be able to listen to several recordings and identify the hall in which they were played. Or whether a recording made in a particular hall was mixed in a way to make it sound like it was actually recorded in a different hall. And of course the impact of different headphone gear on on the above questions. It seems to me that classical music would be ideal to really get a good measure of this. Live concerts (eg rock) which utilize microphones and amplifiers have so many variables that it would be almost impossible to determine Whether it sounded realistic unless the listener was actually there.
