How about a different example. If you know anything about pharmacology, you know they judge medications by how effective they are compared to placebo. Oftentimes, medications are just a little more effective than placebo. Sometimes they get approved, but it's found out later they aren't any more effective than placebo. I'm talking about meds in widespread use to treat all sorts of conditions. In other words, many medications are only a little bit more effective than the placebo effect, which says nothing about the medications and everything about how powerful the placebo effect is. Maybe that's a better example.
Much better example.
Let me just explain shortly what I find to be the best testing set-up. It is better than the DBT IMHO.
Situation: You have changed you favourite IC in your main rig to use it temporarily in another application.
Some days later, you sit down to listen to the main rig - and then you notice that something is not as it use to be, and maybe you can even tell what it is (soundstage, mid-range or whatever). Obviously you are interested why there is a difference, and begin to look if the phones are allright and so on. Then you happen to look behind the source: Oh - right, I changed the IC a couple of days ago
What this test is good at it’s to take away the expectation factor. You are not sitting and expecting
a change. Compare with the Placebo effect. However, you could always argue that you were subconsciously aware of that the cable was changed and that induced the feeling of change. But I do not think that is likely.
If a power cord would pass that kind of test. I would certainly consider it. Once again: I have no experience in power cords, only interconnects. But I am certainly open to that they too can have a significant role to play.
