I've heard Heresy III and IV, as well as Devore O/96. First of all, the Devore looks gorgeous and classy. And sounds significantly better and refined. I'm sorry I won't put the Heresy's even two levels below the Devore. Having said that, I'm probably one of the few who didn't like the O/96 much when I auditioned it a couple of years ago. But at any rate, they are better than anything Klipsch I've listened to. Of course, this is only my opinion and very subjective as such :)
