Speakers too wide apart?

Today on a whim I decided to move my speakers closer together. Originally they were 7ft apart. After the move, they are now 5.5ft apart. I sit about 7.5ft away. 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). Most impressive was how much more holograpic the music is. This simple adjustment had an incredibly profound affect on my system. As others have pointed out on many occasion here on this forum, it pays to experiment with speaker positioning. In my case, I highly recommend adjusting speaker width.
