Yes, that's a good correction. By 'blind' testing I mean subjecting the testers to some sort of a harness. In other words, placing them in some kind of unnatural situation where they tend to lose their sense as to which way is up. Often times such testers pretty much mentally toss a coin in their heads as to which side of the test, A or B, do they prefer. They do that just so that they cold quickly reach the end-of-job. People under any kind of stress, even most minimal stress, tend to work furiously on ending the situation one way or another, and will hasten to do anything just to bail out. That's why I think test harnesses are not good for evaluating our listening experiences. ------------------------------------------------------------------------ magiccarpetride's Profile: http://forums.slimdevices.com/member.php?userid=37863 View this thread: http://forums.slimdevices.com/showthread.php?t=94418 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
