That's not at all what they were doing. They played some musical selections on two amps (invisible to the listeners), labelled A and B or something, and then asked which the listeners preferred. In such a situation people will almost always express a preference even if A and B are identical, and if asked will construct elaborate (and false) reasons for their choice. In fact this setup is almost identical to that of a study I know, where the researchers were interested in this psychological effect (so in the study the options were identical but disguised). So yes, the test was flawed - the results are meaningless (for audio at least) if the participants couldn't actually perceive a difference. They should have checked that first, which would have been very easy to do given their setup. > > Meaning? > As Skunk said - that probably all or most of the amps couldn't be distinguished in an ABX test. That's been shown over and over again with many different types of amps. Their results are consistent with that, as most of the votes were split about evenly. One exception might be the Panny, which I think does an A->D and a D->A. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=33112 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
