I dont really know what the best is, but right now I have on:
9.8
7.3
2.9
-0.1
-5.4
-7.3
2.2
9.2
13.0
15.6
It gives a nice bass boost without forgetting the treble areas. I personally don't like Nullsoft's preloaded rock preset, so i made my own. If anyone knows anything better for rock, please let me know!
