Cleanest clipper I've ever used. Very good multiband AGC and they finally got the wideband AGC right.
Try one, you'll like it. Easy set up too, hard to make it sound bad.
If you're an insane tweaker who really knows your way around audio processing, the other end of the spectrum is the O.9 where every parameter is there for you to adjust. I always tell people that the 9 is also a nice box, but if you're a novice the 11 is a much better bet for you.
When you get the demo, talk to Cornelius over at Omnia. He'll walk you through it and get it sounding exactly the way you want it to.
