@jerryg123 , someone on ASR spent more time evaluating their methods. The word amateur keeps repeating in my head. I will point this out to you as well @kota1 .
The guy doing the switching is there. The two listeners discuss their findings which isn’t good methodology during the test. The switcher also had done the measurements. This isn’t even good single blind. Plus they discuss things for several minutes as cables are switched. They can see the cables being pulled out as switching is done. The first one was a white thin little cable, the next one is a big black fancy looking cable which they might have noticed even though not scrutinizing the cable as this happens. The switcher even gets involved in the discussions of what some of the cables sounds like with the test listeners. At one point even discussing what the measurements of the cable currently listened to was. This is a preposterous test. They are listening to not quite 10 minutes of music once, then talk amongst themselves for 7 to 8 minutes while cables are swapped (again in their view) before listening to the next one. And the results are random even though the author tries to spin it as meaningful.
