Joseph Audio RM7si or ProAc 1sc?

I'm considering an upgrade to the bedroom system. The main part of the room is 18x24x10 with a tray ceiling, and it is fairly dead due to carpet and furniture, but with some slap off the slanted parts of the ceiling. Power is a Linn LK140, Transparent speaker cables. Pre is a Linn Wakonda, and the source is a Proceed cdp. I listen to all kinds of music, especially on the multiroom system (of which this is a part). I've heard other models from both these companies (RM25 and Response 1.5 and 2.5), but I don't know these models. Any thoughts?
