What Rick is saying is very true. I spent tens of hours positioning my fronts and I thought I found the perfect orientation with the massive toe-in that you see on the Wall of Fame. But after 7 months, I moved my 80s for a Paradigm A/B test and when I put them back, I didn't have them toed in at all. I found the soundstage opened up tremendously and the treble was "sweeter". What fooled me with the extreme toe-in was the clearness of the highs. The treble clarity that I thought was good was even more appealing with no toe-in.
