. I was immediately floored by how much better my system sounded. There was a naturalness that I never heard before. Soundstage depth also increased dramatically (which may not be saying much since before I had zero depth).
I keep saying it over and over and over and over and over and over and over - get those speakers far away from the side walls - at least 3 feet if you can!
If your "throne view" photo is anything to go by as to speaker placement then it is not surprising you were completely totally floored when you moved the speakers closer together.
Well done for making such a huge improvement ....at no cost to boot!
