OK, I'm going to make a case for Charles Ives, based on the 1 & 2nd Orchestral sets, Central Park in the Dark, The unanswered question and Symphony no4.
Nick,
It seems that Charles Ives transcends the question of "greatest orchestrator" in that he is one of the most unique musical personalities of all time. What tree did this guy spring from? We can trace the roots of Bach, Mozart and the rest (even though their genius is equally unexplainable.) But Ives mature music (his early stuff sounds like Brahms!) is seminal. Not just seminal but radical. So radical that he doesn't fit in to any time period including his own. Stravinsky pointed out that Ives' polyrhythm's were 50 years ahead of their time.
As far as orchestrating his work, he reaches the ideal of a singular creative idea. You don't hear the orchestration of an idea in the traditional sense. You hear the idea presented as a singular whole with many aspects. In this sense he is a master orchestrator to be sure. I can't imagine anyone finding an Ives sketch and "orchestrating" it, which you could do with countless other composers. (I recently mentioned him in another thread btw.)
Gesualdo is the only guy I can think of that is a unique as Ives.
Thanks for bringing him up.
