OP,
By one microphone hanging… I assume you actually mean two… stereo.
But! Multi-mixing completely screws up the acoutics of the space and hence the essence of the orchestra… when playing multiple instrument. Completely destroys the acoustics.
I have had season tickets to the symphony for over ten years. This is how I learned what real acoustic music sounds like (along with some smaller venue jazz and classical). I have spent hours carefully listening to how the reflections from the venue and the multiple instrument interact to cause the experience. The careful location of the different instruments and the composer has orchestrated those frequently to form huge waves of intense sound that can wash from left to right or otherwise complex pattern.
The very worst recordings I have heard have been those multimiked jobs, the very best late 1950’s with two microphones.
