I see three problems with the proposed speaker wire test, and one piece of missing information. First, what length are the wires? You will want the wires long (to increase the "wire effect"), and equal length (to be fair). Second, you will want to match signal levels AT THE SPEAKERS. Some wires will have enough series to make the speaker output levels significantly different -- invalidating the test. Third, you should throw in a control: two wires of the same type. Perhaps this could be a separate test -- listen to three cables, labeled A, B, and C. Two cables are identical, and the third one shown to have a different "sound" from the others in the previous tests. The listeners will try to detect the odd wire. This test is useful, because people may show a preference for a certain letter of the alphabet. This is psychological testing, and you have to be very careful to account for all the variables.
