I would go with the placette RVC(remote volume control) balanced it would only be $1800, and would everything you can imagine and more! Mikelavigne uses one in his system(which many call the best sound they have heard ever) and it is I believe the cheapest(most out of place, or maybe not?) component in his rig. He swears by it and I wouldn't doubt what he says- many enjoy that the placette products and swear by them, if I needed something like that in my system I wouldn't hesitate.
