Ever attended an actual symphony? Did they hand out spatial enhancers at the door?
There's the apocryphal story of the audiophile who'd never actually been to a live concert, so his friend took him to one. As they left, the friend asked "how'd you like the concert?", to which the audiophile replied "needed more treble".
Thanks. So what's your point?
In a perhaps overly-obtuse way, I was merely attempting to gently challenge your basic assumption, that spatial enhancement is warranted for orchestral music.
As jsg notes above, the concert hall experience, like any live performance, is quite different from listening to recorded music. But isn't the goal of recording to try our best to replicate that experience? Sure, not in all genres, some of which have no connection to reality at all. But acoustical music
is firmly grounded in the real world.
The placement of instruments and the acoustics of the hall make the classical orchestra inherently stereophonic. If you're lucky enough to be seated in the sweet spot of a concert hall, the sound will completely envelop you in a most pleasing way. Replicate this in your recordings and there's no need for electronic trickery to deceive the ear.
I hope my point is clearer now.
