Center Stage?

My system does double duty. Music is my first priority. However, since my system is also used for home theater, I am one of those with the big screen t.v. and entertainment center in the middle of my speakers. Typically, I place a thick blanket over the screen of my t.v. while listening to music. After reading through some threads recently, I am wondering about the benefits of having open air in between the speakers and relocating them to another place. This would require some serious effort on my part and wonder if many of you out there think the work would be worth it? I think it would be helpful for you to know that the entertainment center is a very open design. It has no sides. It consists of two iron towers with shelves and a center piece that spans between. It stands approximately eight feet tall. The speakers are a moderate sized floor standing model. They are postioned so that the front of the speaker is about one foot in front of and a foot and a half to the side of each tower. What do you think? Will my sound stage, imaging, and tonality improve if I give the speakers "room to breathe" in the middle?
