Bernard, the link you referred to is
here , a copy of the Stereo Review amplifier blind listening test that infuriated some audiophiles, but also opened the eyes of others who didn't have their heads in the sand. Among the more notable results was that a $12,000 pair of tube amps that were correctly designed(i.e. they didn't have a flawed "tube sound")were indistinguishable from the $220 Pioneer receiver. Also notable at the end of the article are the usual before-test comments about the "sound" of the various units, which of course disappeared when the listeners had to trust their ears in the blind sessions. One of the "believers" quoted at the end of the blind test(but before being shown his apparent 7/16 result)still thought that he had heard clear differences. The sincerity of these beliefs shouldn't be questioned, but it's also clear that there's no factual basis for them.
