Other posters have already said it, but to add some weight to their words, three worthwhile considerations are room treatments, isolation feet (vibrapods and support cones worked wonders for me), and a Hubbell cryo'd receptacle all made remarkable differences in the fine tuning of my setup.
With room treatments, it can be easy to spot what's add if a friend can help. All they have to do is hold a fuzzy fleece blanket in different parts of the room while you listen. You should be able to pinpoint which areas are reflecting sound the most and add treatment there.
What are the dimensions of the room in question? How far apart are the speakers, and how far are you from them?
