It might just be time to remove the RPA-1, too. I've already moved it out of the center to relocate it to the other side...and now I'm not sure that I want to.
EDIT: Now I think that I'll keep it in the center for now, but I just won't hook it up. I think that I can rearrange and make it look even with the IPS-1 gone, but with both gone, it'll look off. Someday, I'll get a narrower center and put the TV on the wall.
