In the past, we have attempted to explain in more detail, the science behind this technology. Unfortunately, we find that more information tends to bring out the skeptics, so we now elect to remain informative, yet vague. We like to say "most people don't know how the cell phone works, but that doesn't stop them from using it." We feel our products are similar in that it is not critical to know how they work in order to enjoy them.
Yep, and they will still sell them just fine. The reason is because, well, it's basically a kind of religion. Meaning facts don't matter, and they know it. If their customers believe it sounds better, then it will. And if they spend $9,999 on a transfactor wave smoothification box, then they will believe it actually makes a difference. A $9,999 difference.
While those products are obviously snake oil and all the marketing around them is very funny, as I often say about this, I have absolutely zero problem with those products existing and selling.
Are those companies hurting anyone? Not really. Are they taking away business from others? Not even so IMHO.
That people will judge in a 100% subjective way the effects of products that are exactly sold to "improve" their *subjective* listening experience is perfectly congruent.
Likewise, some people (probably even a lot more than we may think) feel better when they are wearing a certain color. You can try and prove them using thousands of studies that it can't make any objective difference whatsoever. That would be barking up the wrong tree.
