It would be good to introduce some sort of "double blind" factor in the
testing.  When I was involved in some critical audio testing several years
ago, we used an "ABX" box that gave either source A, B, or X (A or B) when
switched.  This approach tends to yield data that is less biased by the
testing environment.
