yesterday I was watching the latest Game of Thrones episode, very dialogue heavy episode by the way... Was using the AMP and with the SXFI ON I did notice the reverb at first, in about 5 mins I completely forgot about it. Occasionally I would turn it OFF and the whole image would collapse to my ears. I would put it back ON and it went back to what now I felt was a more "natural" presentation. Definitely much more enjoyable with it ON than OFF. I hope they work out the reverb soon though, but after last night, I realized that at least for me, it is not such a big deal. So far I had been using it for gaming only and then I used my LH Labs Pulse X Infinity for music and movies. It was a pleasant surprise. EDIT: Forgot to add, I am using the Senheiser HD600 with the HD598 profile as it supposedly has a sound signature very similar to the HD600. So far its sounding good. I get the surround effects and the front image feels in front of me instead of an arch above me, which is always nice!
