+there is a little game of connectors and cables going on 
+in the electronics world. not just consumer, but i see it always
+with headphones. it's a real problem. you've got to get your
+connectors to connect without them failing over time.
+and you've got to have cables that don't fall apart over time.
+this may be a time tested ongoing problem like rust. connectors is
+a big one. you've got to get connectors right. like aerospace right. it's
+got to be perfect. 100% of the time. (or six sigma, whatever)

+one use of an x/y mode of scope (vectorscope)
+Audio 
+In audio applications, a vectorscope is used to measure the
+difference between channels of stereo audio signals. One stereo
+channel drives the horizontal deflection of the display, and the other
+drives the vertical deflection. A monaural signal, consisting of
+identical left and right signals, results in a straight line with a
+gradient of +1. Any stereo separation is visible as a deviation from
+this line, creating a Lissajous figure. If a straight line appears
+with a gradient of −1, this indicates that the left and right channels
+are 180° out of phase.
