I haven't heard the 1.4's, but have heard the Special 25's. Without question, if imaging is high on your list of attributes of importance, these are speakers to have your short list. Unbelievable.
I found something a bit odd with the Special 25's. I'm sitting straight-on to them, vocalist dead center between the speakers. Most speakers, I turn my head and the impression is that the vocalist stays in place, and I hear them at an angle. With the Special 25's, I turned my head and the vocalist stayed "in front" of me. It was a weird sensation. It's not that way with the other Dynaudio speakers, including monitors, that I've tried.
