JoeSoft Hear application question

I was looking for EQ for the whole Mac OS X system output sound and found Hear application. I installed it and when I'm trying to equalize sound using Hears EQ (resolution was set to 96) it distorts sound and doesn't work properly. May be somebody knows how to use it correctly, because when I set Resolution of EQ to 32 it seems it works much better, but I am anyway not sure about EQ sliders scale and precision... =/
