Topic: What the stereophonic perspective exactly is?
Demystifying needed:
Is the stereophonic perspective just a shortcut for convenience for some hidden 2 Mic left-right preset more or less symmetrical to the player?
Is it optimized in some way pro instrument?
What implication "stereophonic" has for such a specific instrument as "Blüthner player" - will some perspective characteristics somehow doubled if I choose stereophonic?
