Yes. But it is valid I think to ask questions about how the testing is conducted.  Listening to the same thing 16 times is pretty indigestible, and I doubt even the best statisticians have a reliable method of calulating aural indigestion (or even the effect of needing to go to the loo) over time...

My questions with DBX w/r to hifi is one of methodology.  I don't doubt that it is possible to design a reliable test, but a simplistic listening "blitz" is not a very convincing approach and one I would suspect that *tends* to lead one conclusion.

IME (as a guinea pig), DB taste tests are *never* done (this is IME  ) 16 times. You will be given three or four tastes at a time to evaluate. In addition, some people are better at evaluating cetain tastes than others.

SupposeI was a manufactirer of expensive cables (as an example). What *possible* reason could I have, asuming I really believed in my product for *not* being in favour of testing. If *jaw drop* is not just jaw-jaw, then the superiority of my product would surely be established.

Just a thought.
