On a related topic, it's well known that if by accident or otherwise you lose the use of one of your senses that the remaining senses become more acute. That being the case, has any audiophile out there tried poking out their eyes to improve their hearing? It's probably a bigger upgrade than any sub-$3k power cable.
do blind tests have any practical significance
do the results of a blind or double tests have any usefulness ?
a blind ab test does not prove anything. it only states facts, namely that a certain percentage of listeners were able to distinguish the sound of one component from another.
there are many issues as to the validity of these tests.
the question, "can a listener detect the sonic difference(s) between components", is never answered definitely by one test.
suppose a blind test is administered 10 or more times to the same group of listeners. assuming the first test is replicated 9 more times, there is a chance that there may be an inconsistency between the outcomes of the test.
suppose a statistically significant percentage, say less than 60 percent, for a large sample of listeners, identifies differences between 2 components, what does that mean ?
what is the application of such a result for a prospective buyer of a component ?
