Sautan 904,
The proper unbiased test to run is the double blind test that many of us learned about in our Experimental Psychology classes. You ran, perhaps?, a single blind test. The double blind test is set up like this. One of your friends disguises all three cables. as fully as possible so that neither you, the " plugger in-er", nor the listener knows what speaker cables are being plugged in. They should be labeled with arbitrary meaningless letters or numbers for documenting purposes. In the alternative, the listener should not be able to even see the person who's plugging in the speaker wire. Multiple random plugins of each wire pair should be done. This eliminates any experimenter bias, i.e., when conscious, as you acknowledged, or, unconscious biasing that is transmitted by you to the listener. Also, when you misled the listener about which wire was being played in your test, you obviously introduced bias. Maybe your results will then be the same but you, and we, could then rest assured that no bias has been introduced into your experiment.
