Sounds like a good plan.

Sometimes a single, undivided group is used. Random pattern of switching between two units is used, known only to the test organizers. And while there are only two units compared, participants are told that there are 4 or 5 different units, and asked to rate them from best to worst.

One thing to note is it is best if the people conducting the tests are unaware of that or hidden from view lest they give subtle visual and verbal clues.

I'm all for blind and double blind testing of essential things but at some level it seems of less necessity for testing of basic good audio equipment. If you have to go to that trouble to detect a small difference then you might be overworking the purchase.

I don't think anybody is suggesting that. This discussion is more about the placebo effect and how to eliminate it in testing.
