The best sounding classical recordings (like RCA's Living Stereo and Mercury Living Presence) are recorded in a concert hall from a prime point in the auditorium using two or three mikes covering the spread of the orchestra. This gives a totally natural soundstage. Occasionally they'll drop a mike overhead to catch a detail, then mix it into the natural spread in the right place. The basic soundstage is almost binaural, and includes natural hall ambience and depth cues captured by the mikes.
Jazz combos are often miked as a group with a natural spread in a real room too. This is completely different than the synthetic instrument placement in multitracked rock mixes. Those are blends of close miked, distant miked and direct patch in. Ambiences and reverbs are digitally synthesized on an instrument by instrument basis. There's no soundstage at all. The instrument placement can change with every instrumental solo.
If you take a natural classical soundstage and play it on speakers, the depth cues and realistic spread are projected three dimensionally into the listening room. The listening room's own natural reberberation and depth cues are added to it, making the effect as if the orchestra is right there in front of you. You can close your eyes if the placement is good and "see" the aural imaging in your head.
I haven't heard it, but I'm guessing that if you take a naturally recorded soundstage and run it through crossfeed, it won't sound as natural.Edited by bigshot - 11/6/12 at 12:18pm
