Has anybody got, or have access to, The Wall by Pink Floyd? Another Brick in the Wall part2 has a helecopter in the intro, I've listened to this on my system through both speakers and headphones and also on my wife's boss's megabuck Naim, Linn and Moon system. All I hear is the helicopter starting off quiet then getting louder in the left speaker then move to the right. I don't hear it approach from anywhere other than the left speaker nor do I have any sense of altitude or distance.
What do you hear?
