has anyone else tried Lloyd Walkers latest tweak

Just like some little boys that know vegetables are no good before actually trying :)

It can also work the other way: Experiment, then formulate a theory based on actual data. Then do more experiments to determine whether your theory holds water.

Please don't lecture to me on how science works; I have been a scientist for 40 years and have published lots of papers in first rank journals. Now just show me the data that corroborates the hypothesis that crystals attenuate RFI, and I will be happy. Also, please actually think while you read my previous posts on this subject. I never claimed that the tweak has no audible effect or that its proponents were nuts or laboring under a deception. I am only asking whether or not this effect that they do hear could possibly be due to attenuating RFI.

Mr L: Thinking back to my(at about the age of 10) first electronic project, a crystal radio; virtually the only components it contained were the crystal itself, which was described as, "the detector" & a tuning coil. I'm certain you are familiar with radio waves and their electro-magnetic energy, so- I'll skip that treatise. In a crystal radio; the detector changes the received RF energy(via antenna/tuner) and changes it into an audio signal. The detector is actually a rectifier & when radio was first invented; many found that various rocks, that were crystalline(ie: pyrite, galena, etc), could be used as detectors. Isn't is possible, that these mystery crystals are composed of a rectifying substance that is then sized and shaped to tune in to certain RF freqs, deleterious to our listening pleasure? In the radio app; the audio signal's energy is directed to, and expended by, earphones. I have no hypothesis as to what the crystal might do with what RFI/EMI energy it might capture. Not to start another debate and I have no idea whether they work or not, but- Shakti Stones are purported to function the same way.
