I see you've gone with the diagonal setup there. Looks good and I know from experience that it adds to the holographic sound. My system is in a square room and after living with flat, two dimensional sound I tried the diagonal configuration. Wow is what I said the first listen. It's been a couple years now and still I say wow some nights.
What prompted me to try it was the flat sound I was getting from a pair of Thiel 1.6s I had. I knew they were made to give rich three dimensional sound, and man did they shine in a diagonal setup.
