Thank you for your responses.
I definitely have my eye on Vienna Suite. I'm just waiting for my wallet to catch up with my appetite. However, it only just occurred to me that I could probably learn quite a bit about EQing orchestral instruments from studying VSL's presets. That makes it even more appealing.
I really appreciate your insight, William. Fascinating stuff. That kind of information can be hard to find. If there's a book out there that is to orchestral mixing what Piston and Forsyth are to orchestration, I'd love to hear about it.
That said, MIR is an incredible product, and has taken most of the guesswork out of achieving a fantastic mix. Every time I use this software, I'm astounded at what it can do, and grateful to live in an age where such miracles are possible. So, thank you, VSL team.
