Fascinating story about the party. So to be clear, you're having a social gathering at your house and the topic just naturally turns to your listening acuity and the precision of your loudspeaker/listening chair setup? Okay. And at this gathering some wild and crazy guy decides to play a joke by moving your chair and seeing if you notice? (I can only imagine that copious amounts of alcohol were invovled). Though the chair move was not visible to the human eye, you still were able to immediately hear the deleterious sonic effects. Was the lady as impressed as we are?
