Steve-
But Steven Stone is using the Off Ramp 3. I think this is the 3rd review I've seen him do where he positively mentions the performance of his OR3, and he never notes that there is a new and improved model.
It would probably be worth it to you to give him an OR4 to play with. Good chance he will sing it's praises in future articles. He seems to be one of the few reviewers in the mainstream audio press that understands and enjoys computer audio, without any "buts" or "althoughs".
