I think you're looking to cram a square peg into a round hole here. I've heard the Preludes and they do a nice job of creating a 3D image. In fact, you could probably save some coin for a bedroom system and get the Minuets because they do a great job of that as well (maybe even better). I've heard the Arros too and they also do that great disappearing act and throw up that big 3D stage, and although I haven't heard'em I'd bet the Salks do it too.
Here's the problem, I bet none of them create that magic 3D holographic imaging when shoved up against the back wall -- it'll just crush all those subtle nuances and reverb trails that convey that crucial information. Best of luck in your search, but if I were you I'd just go to my main system if I want that kind of soundstaging, or I'd pull my bedroom speakers out into the room for those times when I'm listening seriously. That said, I think you've got three good candidates here and would also add used Joseph Audio monitors to your list.
