However, ISTM that designing your DBT around the problem of long term auditory memory, gives you a fundamental problem in justifying a DBT methodology that is primarily validated in the drug industry, without any such short term considerations. You are not generally testing the very short term effects of a drug using DBT, and neither should you be doing so with a music reproduction system. What's important in both cases is the longer term effects. The fact that auditory memory is short, shouldn't govern the adoption of a test methodology that's inappropriate to what you actually need to test. Therefore IMV, the only thing that a short A/B test is any good for at all, is to determine whether you can hear a difference between A and B. Adding any additional parameters, such as which is which, or which you prefer, only introduces additional unnecessary cerebral processing into the experiment, which can easily distort the results. -- Patrick Dixon www.at-tunes.co.uk ------------------------------------------------------------------------ Patrick Dixon's Profile: http://forums.slimdevices.com/member.php?userid=90 View this thread: http://forums.slimdevices.com/showthread.php?t=37553 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
