Are you serious?

"Electrical Engineering and design is not science, or rather not scientific investigations"

So the design of an electronic audio product is not of a scientific nature? The act of performing an electrical test on a piece of audio gear is not a scientific process?

Not only is that absurd, but even a properly conducted listening test is in fact a scientific process. That means adhering to DBT protocol.

Did John work for Intel? I can't confirm or deny what I have not seen stated? Where does he claim that? I'm willing to give him the benefit of the doubt here are many people work for Intel. But what exactly did he do at Intel? There is nothing in the bio HE posted on the above articles that states any formal background in electrical engineering or electronics. You think a company like Intel doesn't require that of their engineering staff? Perhaps not for technicians but surely for their design engineers.

And it's not that his products don't work. That's my fault or not being more specific. I'm sure they do "work" in that they pass a digital audio stream faithfully. And I see no reason why his isolation products wouldn't reduce electrical noise on the signal or bit stream.

What "does not work" is the claim that these products improve the recovered sound. Sure in theory you could have enough noise on the bit stream to couple into the analog section of a DAC. But when you consider the magnitude of the average electrical noise level on a USB interface versus the S/N of the analog circuits and post amplification, coupled with speaker sensitivity, it's simply not audible.

Yes, I know you and others claim to hear it. And I believe you honestly do. But have you heard of expectation bias, placebo effect? Would you be willing to participate in a properly conducted DBT?

Or are you one of those audiophiles that say DBT doesn't work. That the very idea of a test destroys the delicate mode, upsets the sensitive listener, and therefore nullifies the differences.

Please!
