@erik_squires Finally got home after a long drive. Play "The Wild Heart of the Earth" by Cécile Verny Quartet from Fear and Faith (album) to test out the "crossing in front of the listener" idea. Immediately the first impression is the shrinkage of the sound stage. Switching back to slight toe-in position and everything gets back to normal. Sorry, Erik, as much as I appreciate the thought, I am not sold on this thinking outside the box idea. However, with the height of the stands, I was actually listening below the vertical axis of tweeter all the time when I lean back on the recliner.
@stringreen I do not disagree the magic power of a good paring of headset and dedicated amp. However, I could not endure wearing headset or In-ear even for half hour. The discomfort from even a high-end headphone just sets off my enjoyment of music listening.
