I haven't heard the Sophias. But, I have listened to the Duette and Alexandria. If I could afford the Duette, I could easily live the rest of my life without ever buying another component, except as a replacement for wear.
I did not find the Wilsons to be colored in any way. I heard them with CJ solid state gear and they burned their synergy into my brain permenantly. The Wilsons do project their sound forward quite a bit, but I didn't get any sense of pushiness like most speakers that are forward give me.
Yup, Wilson will be my final speakers at some point.
