On a second thought...
One might find the Axe already too overwhelming in the sense of tweaking and fine-tuning, while the Kemper is almost like a plug and play thing, but still offering you the needed amounts of tweakability, and nothing more or unnecessary. Not to mention it's considerably cheaper than the Axe in Europe. I'm still going to order the KPA as soon as I have the money... I just hope that all the bugs and reliability issues will be fixed and some sweet improvements and new features will come along sooner or later.

It's funny how Fractal Audio is trying to copy profiling immediately... the Kemper really raised the bar on "modeling" equipment, hasn't it? The Axe is nowhere near as innovative in a sense than the KPA.
