Eldartford, I have said that the disc which is treated sounds louder than one which is untreated. The phrase "sounds" is perceptual. I would not assert that it actually increases level. However, that is what it sounds like, there is that much of a change in the sound when discs are treated. The entire performance seems much larger, more clean and extended, and louder. On an $80K rig with true full range speakers it's not subtle at all. I have never had a skeptic fail to be swayed after hearing the results. Neither the previous-skeptics nor I have a difinitive explanation, but the results are - yes - undeniable.
Your analogies to UFO's are strained. However, I did see a UFO once. It was orange and triangular, and I do not recall it making a sound, though tried listening for it. It flew like an airplane (straight, not terrifically fast) but, again, it made no sound. I was about 12 at the time, and I told my parents. They scoffed at it, until the next moring Paul Harvey speaking through the kitchen radio announced, "Numerous UFO sightings over Northern Illinois and Southern Wisconsin last night..." My mother was in the kitchen - you should have seen her face! The UFO was a plane painted with gray and florescent stripes taking air samples at dusk as it was flying North. In the twilight at its height it appeared to the naked eye as an orange triangle. The lack of sound was likely due to the influence of wind.
Perceptions are not always wrong. The answer to what lies behind the perceptions is usually logically explainable. However, to scoff at someone who is experiencing something perceptually is often nothing other than arrogance.
I happen not to believe in aliens. I hold that all "UFO" sightings have logical, natural explanations. However, that does not stop people from seeing things which they cannot explain.
Similarly, when individuals like myself report as accurately as we can the experiences we have when conducting listening tests, it's not helpful for someone to argue that we are delusional (placebo effect). So, kindly get off your arrogant UFO analogies. :)
Shadorne fumbled the ball. How would you like to conduct the simple disc treatment/listening test? Will you take the same position that because you already "know" it can't change the outcome you won't conduct the test?
If so, we are assembling a very interesting case study for objectivist behavior. :)
