Are Shakti Stones effective?

From my understanding, they're supposed to absorb RFI/EMI. I've never used them but do use other products that do similar and have been impressed.

First I read about bricks, now stones. If the size keeps getting smaller,
it's gonna get messy, pebbles, then sand. 

Instructions for use: Bag first, do not apply directly, may be messy, may cause irritation if ........:-)

Yes they hurt if you throw them at someone. 

The best most experienced dealer I ever met stayed with me one time for a couple weeks when he was moving out here to Washington. He brought a whole van full of gear, and I got to try it all. Among the many tweaks and cables and amps was a Shakti Stone.

I was no stranger to tweaks at this point and real eager to hear what it could do. Tried it all over the place. Straining to hear even the slightest difference. The only place it did anything at all was over the transport section of the CDP. Even there it was barely noticeable.

When I told Stewart I tried it the first thing he said was did it work over the transport? Because that is the only place it did anything. So in one fell swoop I learned yes indeed tweaks are for real, we both had the same experience, and Shakti Stones are a waste of money.

Unless of course you like the looks. They do look better than a phone book, which is the performance level they are competitive at.
