Arm, how did you do your blind test, just with a speaker selector? You have to recalibrate each speaker each time you swap to something out. Also, did you have the speakers side by side, or did you remove the speakers/replace each time, you can't just set them side by side.

My guess is you didn't perform a true Blind Test as done by labs or speaker manufacturers.
