Let's not use the term placebo. The correct terms are type 1 error and type 2 error.
What we call "placebo" here is a type 1 error: incorrect rejection of the null hypothesis stated as "Equipment X and Y sound the same." (null as in no difference) It's an error of commision.

When the listener doesn't detect a difference that is clearly there, that is a type 2 error.An error of omission.
NOT A "nocebo", which is a negative reaction where there should be none and is still a type 1 error.

Have you been reading Dawkins & Shermer?

Probably yes, I've read quite a bit on skepticism a long time ago. That thing above is just my love of statistics.
