I also agree with those near the beginning of the thread (I think Newbee was one) who stated that the recording itself is the very biggest factor in creating a "you are there" experience - a far bigger factor than these other factors under discussion for most of the thread.
I was one of the people who suggested this earlier in the thread. In my view, the illusion that "you are there" is created by ambient cues during playback. The biggest determinant of ambient cues during playback is the recording. Then the listening room. Then the equipment.
I suspect the reason so much discussion has focused on listening rooms and equipment is because the characteristics of recordings are outside the audiophiles control, except in the sense that he can make an effort to find recordings with interesting ambient cues, as Al pointed out. On the other hand, listening rooms and equipment are inside the audiophiles control. So, while they have a lesser role in creating the illusion that you are there, discussions about them may lead to conclusions that are more actionable.
It is simply not a high priority for most engineers now to recreate the actual sound of the hall. The engineer adds digital reverberation to create a false ambience
As you seem to imply, recordings of this kind DO contain ambient cues, but they are not ambient cues of REAL recording spaces. They are ambient cues of VIRTUAL recording spaces. I suppose there is no reason why, in theory, a virtual recording space couldnt be as interesting as a real one. In practice, the best recording spaces I have heard have always been the real ones. So it is regrettable that they are becoming less and less common.
I want to hear what that orchestra sounds like IN THAT SPACE For me, [there] are much more important traits for a system than "neutrality," though I don't propose to start that discussion all over again. I am merely trying to explain why musicians place such a high priority on soundstaging and imaging. They are crucial to creating a "you are there" experience.
I agree that, for many recordings, creating the illusion that you are there greatly enhances the listening experience. I also agree that soundstaging and imaging are crucial to creating the illusion that you are there.
However, I believe that soundstaging, imaging, and the illusion that "you are there" are all connected to the characteristic of neutrality. I am hesitant to mention this, because I dont want us to get trapped back on the infinite staircase of our neutrality discussion. So, leaving the term neutrality out of it, and using the somewhat less controversial term coloration, I would say that many colorations diminish the illusion that you are there. Here is an argument that expresses one of the reasons why:
(1) Decreasing colorations tends to increase resolution.
(2) Increasing resolution increases the audibility of ambient cues in the recording.
(3) Increasing the audibility of ambient cues in the recording enhances the illusion that you are there.
(4) Therefore, decreasing colorations tends to enhance the illusion that you are there.
(5) Therefore, increasing colorations tends to diminish the illusion that you are there.
There are various qualifications and exceptions I would make to the argument above, but it captures the spirit of my view.
