Hypothetically, if someone made a CD where the left channel and right channel information was exactly the same _except_ that one was coded exactly out of phase with the other...

Could one then play the CD, have different interconnects for left and right, then at the end of the interconnects merge them with a y adaptor and see if a signal comes out. My thinking being if the interconnects were identically transparent you'd get perfect cancelation. If they differed then you'd get a signal which you could feed to an amp and listen to. Then you'd hear what color one might be contributing to the signal.

Just curious.
