Wywhcan has the easiest solution. If your speaker set up is symetrical but your room isn't then don't expect balanced sound in the listening spot. I've been toeing in and out for months and discovered if I toed the left channel speaker more, which has a sofa beside it and about ten feet of room to the side wall, then it sounds balanced with the right channel, which doesn't have as much room. I'd read somewhere that you should just experiment until it sounds right and don't worry about the aesthetics.
