All this talk of DBT, could anyone provide a link to any such reputable, controlled testing done in audio, including the statistical manipulations used to obtain the conclusions, so we at least know what we are arguing here? Anyone care to philosophize on the great fallibility of science in general, or even specifically on the science and statistics involved in any such testing? Alan Chalmers, anyone?
Why is Double Blind Testing Controversial?
I noticed that the concept of "double blind testing" of cables is a controversial topic. Why? A/B switching seems like the only definitive way of determining how one cable compares to another, or any other component such as speakers, for example. While A/B testing (and particularly double blind testing, where you don't know which cable is A or B) does not show the long term listenability of a cable or other component, it does show the specific and immediate differences between the two. It shows the differences, if at all, how slight they are, how important, etc. It seems obvious that without knowing which cable you are listening to, you eliminate bias and preconceived notions as well. So, why is this a controversial notion?
