... done by someone on hydrogenaudio http://www.hydrogenaudio.org/forums/...pic=33951&st=0 I won't give away the result.... I hate to say this, but the protocol for Phase II is not scientific. "Seven in a row" is not a significance test, and the criteria for having to be "in a row" has no meaning in such a test which allows for the probability of occasional error even when differences exist. In addition, at least in the English version there is no discussion of how the blinding was done, or how long / what type of musical excerpts were heard. Moreover, the switching seems to be in the hands of somebody other than the listeners (although this can only be implied). Please don't interpret this to mean I believe the cables sounded different. I am not a big believer in that ... in fact have always been pretty conservative when it comes to cables. But it does illustrate the difference between "publishing" a test for scrutiny and acceptance, and simply alluding to "years of evidence" or "xxx ran seven tests which showed....". That is why I recently have begun asking for specific references to the tests alluded by some here supporting the use of quick-switch, comparative DBT's for open-ended evaluation of audio components. Anything other than specific tests that can be analyzed before acceptance is simply not adequate support. |
