This is the best audio app I have... You can crank the EQ to fit the worst setup. The only thing I can find wrong with it is that a beginner would have trouble with trying to find the best sound with the equalizer because of the user interface, I find myself not playing with the EQ settings all the time just because of how touchy it is. Dont let it stop you from being creative this is a beautiful app... BUY IT!!!
