I believe that audiophiles are chasing a sharper definition than the real world. In the real world everything just blends together into a wall of sound and through the reverberations of the room. There’s no stereo effect and crystal clear "instrument separation". In the real world most live performances are way too loud and confused. Soft jazz, acoustic music and orchestral music avoid that problem.
@kokakolia I agree. I think the recording engineers enhance the 3D imaging/soundstage to compensate for us not being able to see where the musicians are placed in the performance. I confess that while it might not be true to how a lot of live music actually sounds, I like it and it enhances my listening experience. One good example is “Like JT” from Patricia Barber’s Companion CD where it’s clear the engineers worked to add a sense of depth, but damn it sounds so good I could care less.
