has anyone else tried Lloyd Walkers latest tweak

I suppose it should be mentioned that Acoustic Revive's little QR-8 smokey quartz crystal is also recommended for the cartridge body, along with other resonance targets of opportunity. Of course, be wary of over dumping.

From Acoustic Revive's web site:

"Quartz Resonator QR-8 is not magic or occult. Reason why the sound improves by using QR-8 is that because, by placing QR-8 onto an agenda which causes resonance, the resonance frequency of agenda changes and it stops any resonation. Agenda such as plug, connector, parts, equipment switch, equipment housing, and door in the room, windows, wall, floor and ceiling resonates by its particular resonance frequency and by placing QR-8 will change the frequency and stops the resonance. But placing QR-8 to an agenda which does not resonate, adversely QR-8 may cause it to resonate or to over dump. So you have to be careful where you place the QR-8. You can check if QR-8 is causing the agenda to resonate or over dumping by listening to the sound."

Maybe in one of the parallel universes(quantum physics), we could actually see the effects of the crystal.

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.
