I had Kappa 7's for many years and went to Revel Performa F32's. I was looking for a different sound though. The Kappas did a lot of thing well and my first priority was the retain the detail of the Emit Tweeters, but I was always a little disapointed in the mids and the Revels seemed to bring that out in a more natural presentation. I had also considered JM Labs Electras at that time too. You don't mention a budget but the Paradigm Signatures are doing some pretty awesome things for their price range. Also the Studio Series V4 are sounding unbeleivable for their price range.
