Technical and scientific discussion of amps, cables and other topics.

RE: you make the classic mis-assumption...

of many test naysayers that all "double blind" testing involves rapid ABX switching. That is not an inherent requirement of blind testing. One can concoct a testing scenario where you are given whatever amount of time you wish to listen to one configuration before listening to the other.

The only requirement is that the test subject remain blind to the specific item under test (the first blind), and that immediate test administrator who has contact with the test subjects also be blind (the second blind.)

The only goal of any blind testing is to remove the conscious and subconscious influence that specific knowledge of the item under test brings. Remember that such biases don't always follow the lines of expectation.

If there is a valid difference, it will show up repeatedly over time. The problem is that such tests are never easy to set up to the satisfaction of the varied interests. In fact, a certain segment of the audio world wouldn't even want firm results. Uncertainty offers them far more security than the chance that tests might not go their way.
