Are Shakti Stones effective?


I have never used Shakti Stones and wonder if they really work and, if so, what do they do,  I have used the Shakti Holographs and found them to magically focus the sound and tighten the soundstage. From what I have heard, even from Shakti, is that the stones make a significant difference is some usage and less in other. Has anyone used these and what do they do?

With my similar products, no strain was needed to hear the positive difference.

Shakti and similar products don’t use mass as their effectiveness. In the products I use, use rare earth minerals that absorb RFI/EMI, I only assume the Shakti does this as well.

I'm not histrionic about it as one here is.

Once you get  them,Then what do you do?
You put them on your head, to remind you of a bad "snake oil" purchase, and never to do again.

It would be refreshing if those immediate naysayers on these types of thread could prove they’d ever tried the mentioned tweak before they pull that ’no, it will never work because it can’t claim.’ And Miller Carbon’s responses to this are what I mean as useful answers - he tried it, he sort of did hear a difference and he points out anything of sufficient mass placed on top of a cd transport usually does effect its sound.
for me i am not an IMMEDIATE naysayer

i have tried it, gave it a chance (actually many many chances), based on my experience, it does nothing i can hear - still have one, it sits in my equipment closet after four homes in 20+ years

but maybe i am blessed with no emi issues... or poor hearing LOL

ymmv as always
