Lai, 100% agree. I really really do.Many are the physicians who have prescribed sugar pills to great patient benefit. If it works for you obviously keep it!
But...But beware of situations in audio somewhat analogous to Münchhausen's Syndrome, in that the audiophile unwittingly HAS to try solutions, that are proven scientifically impossibly unable to improve sound, because of an intrinsic need. If it is inexpensive enough, generally really no harm(and I guess this would be wallet dependent), but if carried to extreme, it would represent a detrimental "syndrome". Often coupled with dogmatic defense in the face of valid criticism, this situation would be less than ideal. I believe all of us have seen this behavior amongst the audiophile population. However, if one really believes anything makes the sound better, bearing in mind the previous cautionary imperative, more power to you!!
Any study, including double blind, nearly measures response numbers. Almost never are they anywhere near 100%, the reason for statistics and probability. The two standard deviations or "95%" probability of the result not being due to chance Never, ever states it is the correct result absolutely, just that it is the statistically correct chance of being the result. We scientifically accept that, but never deny that it might be incorrect. Many audiophile fringe issues seem like this. The real issue is absolutely 100% we all do not hear the same and this, perhaps more than anything, answers the variance in audio perceived benefits.
stfoth, yep but kinda dropped psychotropic studies, shifted to anesthetic agents, which when you think of it, are the ultimate big gun--knocking you out, rather than fine tuning sensations, so kind of boring in comparison.
