I also have Focal Sopras like Rick and have had very similar findings about them. I do not find them bright or fatiguing and have them tipped downward (leaning slightly forward) which brings the tweeter more in-line with my ear level. The two things that have made the most difference with mine are the leaning forward and new home made diffusion/absorption panels to cover my tv when I'm not using it, which is most of the time. I like mine toed in to the point that the "beam" crosses behind my head, so they are not aimed directly at me.
I have heard/read more than a couple times that Focals tend to be bright with any models below the Sopras. The Kantas especially. I can't confirm that as I've never heard any other than my Sopras, but again I don't find the Sopras bright so maybe there's something to that.
