has anyone else tried Lloyd Walkers latest tweak

Perditty, I suspect that what is behind the confusion in your exchanges with Benjie is that your 8-19-13 post gives the appearance that all of the post is being addressed to him, but you probably meant only its first sentence for him.

The word Crystal triggers the skeptical part of the audiophile brain, the part of the brain that figures anything new or not in High School textbooks must involve ritualism, psychoacoustics, psychological effects like expectation bias and placebo effect, subliminal advertising, new age mysticism, or hypnosis. I suspect it was for this reason Lloyd refers his little black thinggie as a "crystalline structure," you know, so as not to scare or upset the skeptics.

And the word geoff triggers the skeptical and intelligent segment of the audio community to avoid snake oil salesmen.

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.
