Also note arny, that all source players were considered of exceptional quality (both digitally and analog), would you consider a Magneplannar III exceptional? Do you think an average listener could be able to decern the difference between say the 45 wpc Pioneer and say the NAD? They most certainly did in that review. And that was not even using the NAD's full ability.
Edit: also note that of 15 of the 25 people tested were correct over 50%, so I would state that when averaging this test, that the persons that failed, brought the over all averages below what I feel is real world.
