No, there's no equalizer for MPD, nor are there plans for such a beast. Any kind of software that fiddles with frequencies like this can also be concidered distortion, and it is concidered a much better thing to do this in hardware. Cheap amplifiers/equalizers can be found at a pawn shop for about $20 bucks. Alternatively, you may be able to find a jack output plug-in to do what you want.
So my question is the following. Is that statement true? I searched on hydrogenaudio forum, and I have found this topic which seems remotely related. Not that I think I could hear the difference between a good and a bad equalizer, mind you, but if an hardware one is as cheap as the MPD wiki proclaims, I might just buy one anyways.
