If anyone has any worries about the HD650's soundstage, imaging, or highs, then load up the latest remaster of Pink Floyd's Dark Side of the Moon, close your eyes, and listen. It is a surreal experience. It was an out of head experience.
I was just getting to know the 650s soundstage with the Wandering EP by Yosi Horikawa. I'll revisit DSotM as well.
