Vandersteen Sig 3, Classe -cap 151, preamp?

Vandersteen Sig 3As powered by Classe Cap 151 integrated amp searching for preamp. My large tiled cathedral ceiling room with a wall of glass provides a rigid background. I am hoping to add an element of warmth. Also, often listen to satelite (DirecTV) music stations, I know , not the ideal source. Can that signal be enhanced with additional components?
Maybe a bit, if you use a tube preamp. But the hard surfaces in your room, and the high ceiling, will continue to be a problem. You will almost certainly need to add some room treatments -- absorptive surfaces and such -- to modify the room's acoustic characteristics. There are number of posts in the archives on the subject of room acoustic treatments.
