Okay, this is how I have my speakers set-up. As mentioned they are placed on the long wall, 7 feet apart, 51 inches from the front wall and 53 inches from each side wall. I am stitting along the back wall, about 9 feet from speaker baffle. As far as toe-in is concerned I have found a small amount to be beneficial. The best way to approach this is to choose a few different recordings you know well; I suggest a simple vocal, a small jazz ensemble and a large orchestra piece. By pivoting the speaker on its back spike (do this carefully, if your stands are reall heavy you will probably snap the end off the spike) gradually increase the amount of toe-in. Go in increments of no more than a 1/2 " at a time and carefully listen to each recording after each change. I found that the image just seem to snap into place with about an inch of toe in - not much change in position but a clearly audible improvement in image focus. I cannot predict if toe-in will work in your system. I know that Divergent does not recommend it, at least for the older version of the DeCappo, but at least one of the review magazines (TAS/HiFi+/enjoythemusic?) also mentioned that this was beneficial.
