I've only used winamp and poweramp. Ended up buying poweramp because I like the eq features and the UI looks more slick.
Like I said before, if you get the free "Equalizer" app, you don't have to worry if your favorite music player doesn't have an EQ. It works on all sounds: ringtones, games, youtube, everything. But it also has preset detection for many players including winamp and poweramp and many others.
I think you'll need gingerbread though.
