As a current owner of an Ori and someone who's heard Atticus & Eikon at length on multiple occasions (comparing them to the Ori), I must jump in...
Tonality comparisons are obviously of great interest to all of us. But IMO any comparison of Atticus vs Ori should touch on the difficult-to-define planar sound of the Ori, subtly different from any dynamic driver, including ZMF's. All the planars I've heard (Ori, LCD-2F, LCD-3, AFO, Meze Empyrean, Final D8000) have a characteristic quality of calm/stillness, with notes seeming to explode out of nothingness. I suppose this has something to do with distortion. Whatever the reason, it's a "planar thing" I've come to really really like.
Also musical dynamics seem subtly different on planars. Even planars w/great dynamics (like the Ori) don't seem to jackhammer music into your ears.
Overall, there's a quality of finesse & refinement to planars that I just don't hear with dynamics--w/the possible exception of the Auteur, which during brief auditons at CanJam, seemed to have refinement to burn, especially in the midrange.
