My experience using the KPA for recording is I'm always sacrificing something to make it work in the mix with my band, which means I'm almost never happy. Even reamped for the 5th time on a particular track last night. Articulate profiles cut too much and the treble gets ice-picky, not to mention often lack "body"; darker profiles "fit" better but I lose pretty much all the character I worked to track and it gets lost in the mix.
KPA is a great tool for live use, but I'm really unhappy with it for studio and recording purposes.
