Nice. I'm having trouble w/ 1, so I'll just toss in Dmitri S. (I don't know that symphony at all, but I'm sure it's fine). Took some shuffling (e.g., the obvious Gorecki 3 changed to 4, which if you haven't heard it ROCKS!), moving Mahler and Brahms etc. Of course the best list would include Mahler in all positions except 8!
1. Shostakovich
2. Brahms
3. Mahler
4. Gorecki
5. Schubert
6. Haydn
7. Beethoven
8. Bruckner
9. Dvorak
