I think the general path you are looking for is that if you logically want to raise a single band of EQ by 10db then what you really want to do physically is cut the level of the other 9 bands by 10db leaving the one you want at 0db cut. If you want to adjust the level of your player at the end of the chain to get a final volume that's probably a good feature to build in but in general I *think* that the final level in mplayer should be viewed as a way of leveling different audio sources as different audio files have a small/large degree of variation in overall volume.
