Some people can hear the difference in the polarity coming out of a set of speakers.

try it...

If you made pin 2 hot on both channels on one MTR-12 and played that back on a different MTR-12 with pin 3 hot it would be in phase, no problem. For a signal to cancel out because of being out of phase it has to be with respect the same source, for the most part..And as already stated as long as someone is aware of the pin out.
