So this means I can't move my head anymore when I listen. Not one millionth of a centimetre, I gather, Well, hum... Let's see, how about a head vise (no not lice) with laser level type things to make sure the well seated (and heeled) audiophile does not move and consequently lose any of the phase accuracy of his interconnects, speakers or of his equally expensive (or more expensive is even better) speaker wires. Never mind subwoofers, there's nothing down there any ways, but 12 K cables get the imaging just right, not to mention inner detail and the greater distance between musicians in the orchestra. Magnificent, great I can hear the rosin on the bow now... it's, it's, it's in phase! Glory be to the small, dishonest, inefficient manufacturers for in these anti-scientific times, they shall rule the biz.
