If you had a choice between two smart powers or a quad 909 power amp with a all cyrus system but felt your midrange was a little thin for a set of Proac D28's which way would you go. I enjoy my smartpowers but know that a little thicking wouldn't hurt either for my listening tastes. (metal). If I wanted to go to the cyrus mono X's that would be a 5500 touch vs a 1000 for the quad 909 in NA
