When it happened I knew.
I was sitting there, eyes closed, 100 %in the moment.
The soundstage literally extended beyond/outside the boundaries of the room and the musician began to move across the stage towards me (left to right). It was the coolest moment I've ever experienced. It was so real, I felt like I wasn't alone in the room. I had to open my eyes. It was incredible.
In my mind there was a form, I'd use a sun spot as an analogy (look at the sun, look away) but it was dark like a storm cloud not bright like a light.
I've had a similar experience since but never like that.
I've never experienced anything close to this. The most I have noted is the center channel seeming to be on when listening in stereo only.
