I knew a guy who had this rectangular plywood rig on wheels that was set up in a vertical manner so the it bisected his speakers and reached the listneing postion. Along the vertical edge he had the frame cut to the proportions of his face. He would sit leaning forward with his face inserted into this rig during listening sessions. He claimed it helped with stereo seperation. I would have paid money if I could have photograohed him with "Sildenafil Citrate Ears" on while leaning into this contraption.
