Without a perfect replica of the performance space, - i.e. a lot of careful sound treatment in your listening room, you probably won't get close to a 3D experience using two speakers.
If you must have more than what you are getting, either invest in considerable room treatment, or consider a 7 or 9 channel AV surround system. The problem with that is that I have yet to hear an AV system that has components that match the sound quality of really good high end audio-only gear.
