3a decappo's or proac 1.5 for cary 300sei

I've been looking for a nice simple intagrated tube system, for the last few months just by gathering imformation from this site, and this is what i've narrowed it down to. I listen to classical,jazz and rock music. My room is 10x20, and i listen to my music at normal to loud levels .My current system is all solid state gear, a DNA 2 deluxe,threshold fet10e, and dynaudio 1.3se's.This combo sounds good to me, but i would like to give tubes a try.
