Try placing them about 10 feet apart since you are sitting 10 feet away. Experiment with toeing them in and not.
Right now they are a litte over 11 feet apart with a slight toe in towards the center sitting area. I will say, if the 80s sound that much better, I am not sure I would ever leave my basement if I got them. I have to say, if I did not have the Onkyo I am pretty sure I would be getting the 80s.
