Shakti Stone

I have both the old version and newer 'air' model, tried them on virtually every component. In general they have this tendency to provide the blacker background thing, problem is they tend to darken the sound unnaturally, some of the life sucked out. Certain freq affected, perhaps a bit of micro dynamics lost as well as some spaciousness in sound stage. I purchased many years ago, have continually experimented with them, haven't used them on a component in years, currently using one on breaker box door directly in front of dedicated audio system breakers, this mostly  just to get use for one, can't really say if its having any effect. I will say if using on a component try spacing them slightly away from sitting directly on component, this mitigates the darkness somewhat such that I could imagine it could help in certain situations.

Yes, the 'device' has magnets and other stones within it....I can read the copy at the sites....😒
This one still wonders just how the 'it' and it's arrangement of 'bits' was arrived at in the first place....much like the composition of exotic cables deigned to improve signals and the blurbs exhorting same....

The religions that stalk audio enthusiasm have a marked quality that remind me of religions in general.....

We can't prove Heaven, Hell, or an afterlife either...or one's god for that matter.

Faith should be limited to the mortal plane until some essence of quantum concepts raises the bar into that realm....then, I might be swayed to knell.

I was raised Catholic....got tired of the guilt exponent within it....

Parents didn't want me to be a 'heathen'... and I couldn't feel comfortable with a Bronze Age belief directing my life.

Extend that into my audiophila unless you've more than a blunt instrument.

I bought one because I'm a big believer in reducing EMI effects and tried it on various components with no apparent benefits.  I was about to write it off as snake oil until I rechecked where the transformer was located in my 1990s Krell preamp.  I found a Youtube video that showed a much different location than I had thought.  When I then moved the Stone to be on top of the transformer, I believe it helped with both dynamics and detail.  I'll probably buy another soon and experiment with placing it on my phono preamp transformer.  I'm very skeptical that it would actually benefit all components, but transformers notoriously emanate EMI so I think amps are the best use for them.

Yep, transformers, hard drives emanate much EMI/RFI. Good one is to try on power conditioners.
