The test was poorly designed for that application. A/B tests are bad - you want ABX or ABXY. The reason is that on that test, if you thought you heard a subtle difference you couldn't be sure if it was your imagination or real. You could in principle have ultrasensitive hearing that could distinguish tiny differences in the two supposedly identical pairs, and then you would *correctly* answer "different" for -every- pair, scoring a 15/30 or so. So the test cannot distinguish between superhuman hearing ability and random guessing - not good. A much better design when you want to determine whether two sounds are audibly different is ABX - the listener can hear A and B as often as she wants, and then decides whether X is A or X is B. The question really being asked is whether X is closer to A versus closer to B, not whether A and B are absolutely identical (which could be problematic for the reason above). -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=52501 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
