Excellent text Earl, innit?
You're far too erudite for this place. :green:
Looking at the photos of the speakers in situ, and having had first hand experience of your listening area, they shouldn't work. But, I bet they sound sublime.
Your system rack looks minimalist and better I think than what you had before.
I wouldn't worry about many further tweaks such as component isolation and different brand cable, it will drive you to distraction (and possibly, nuts). Obviously things like a new rack will help, aesthetically if nothing else, but I wouldn't worry if the amp is on metal feet or oak cones, for example. If the synergy is there now and the system is singing, just enjoy it and buy loads more music. You know all those French and Italian Eurovision wannabe's are calling out to you.
Hopefully see you in the new year when it will be my turn to drive griffo down, so don't go changing anything. Print the warning posters now.
