has anyone else tried Lloyd Walkers latest tweak

Al thanks for clarification

Your skepticism is well placed, I know it sounds ridiculous but I can't deny what I'm hearing

Really, Geoff. Is it not legitimate to ask questions about such a claim (the notion that certain crystals can absorb RFI or EMI to a significant degree that would result in an audible effect in the average living room)? Or is it you, in fact, who wants audiophiles to behave not like high-schoolers but like pre-schoolers? "Open up wide now, and eat your crystals." I don't say it can't be true, but there must be some support for it in peer-reviewed scientific literature, if it is true. I can find none. Or are you also saying that science has nothing to offer in these matters?

And to those who hear a difference (Perditty): Be aware of the power of the placebo effect. A good test would be to bring a friend into your listening room who has no idea what the subject is, and test him or her for differences in sound with vs without the crystals. By the way also, RFI is detectable, and a reduction in RFI should be measurable.

Right and it's human nature to expect an improvement when spending money on fantasies such as this. IOW, you're hearing what you want to hear.

I suspect audio applications of crystals has not been peer reviewed. Any more than Mpingo discs, Schumann frequency generators, Shakti Stones, the Tice Clock, holographic foil, WA Quantum Chips, tiny bowl acoustic resonators, coloring CDs, and a bunch of other things have been peer reviewed. I suspect two reasons crystals haven't been peer reviewed are the science community is unaware of this application of crystals AND if they are aware of it they might be just a tiny bit apprehensive about tacking such a subject, if you know what I mean. If you think some organization such as AES is going to run out and sign up to look into crystals any time soon, I wouldn't hold my breath.

I put the post out to see if anyone else WHO HAD ACTUALLY TRIED THE THING heard what I did and it seems one other person has had a similar EXPERIENCE.
As I have repeatedly said skepticism [particularly in this case] is a good thing, but to dismiss, out of hand, with NO experience is nether helpful OR scientific. Again first observe then speculate.
