CraneSong EQI have experimented with cranesong ibis eq, which is an outstanding eg and had great results. But, you must understand that eq's are all about filtering. They do a really good job eliminating any distortion but also some detail at certain frequencies. The only thing I will say is for you to try it out. I decided to sell the ibis and go another direction which I have done a lot of ugrading capacitors until I have found the right combo of caps to make my system extremely neatral. Good Luck!
