From the quote below (have I read it wrong?) they compared a high end cable with something far thinner than a freebie wire?

''To further acquaint the participants with the ABX procedure, the MIT cable was compared over two trials to 30-gauge wire wrap wire. (Thirty-gauge is not much bigger around than a human hair.) The difference between MIT and 30-gauge was gross and audible''

Perhaps 6 out of 7 DBT'ers correctly identified the naff-o-cable?
