Maril555,
The approach I finally took was to start small and focused and expand from there. I worked with an equilateral triangle set up with the speakers six feet apart toed in to my shoulders. This worked great for centering the image. The problem was all instruments were on top of each other and no depth. From there I made the triangle larger. There were a couple of spots where the center focus completely fell apart (one of which is where I had originally placed the speakers). At about nine feet I ran out of cable and could not go further. The center image was solid, breadth was good, depth was poor. Eventually, I was down to toe-in from 0 to about 15 degrees. Trade of was center focus versus soundstage breadth. Finally, I just split it down the middle.
I think starting with the small triangle worked because it took the early reflections out of the equation. As well, I think the toe-in has a similar effect. In a properly treated room, the toe-in might not have as much of an impact. But I think the problem I was having was related more to first reflections than anything.
Depth is still an issue and I assume there is not much to unless I get the speakers further from the wall.
