It looks like a worthwhile test. Some comments: Would it not be better to use a fairly high end system? Even high end headphones, rather than $300 ones?
Secondly, if the ears of the listener are so good that he can note down the differences, why not ask him to say which an unknown player is? This would be an ABX test - you play A and B, to the listener's satisfaction, then ask him which X is. If he can get this right, it would be really strong evidence for a difference. Thirdly, could you randomise the inputs for each test, i.e. in test 1 A is the CD, in test 2 B is, and so on. Then the listener could say which he thinks is the best. If he consistently chooses one, above statistical likelihood, then you have evidence. This is a lot easier to run than ABX. Finally, it's worth getting in someone who knows statistics to help you to decide how many tests to run. -- adamslim MPD on Linux PC, Caiman, DIY Kondo M7 pre, 6B4G SET, Lowther monsters SB3, Charlize 2, DIY open baffle speakers Boom x 2, Radio ------------------------------------------------------------------------ adamslim's Profile: http://forums.slimdevices.com/member.php?userid=7355 View this thread: http://forums.slimdevices.com/showthread.php?t=88364 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
