Are Shakti Stones effective?

I dont know for the shakti stone or the hallograph..... But i create my own devices,with only homemade component, and they worked for improving sound on all count....Peanuts costs....

But people dont believe in their own ears experiments and dont believe in improvement if they are not ready made and officially stamped by a reviewer and costly like the wooden hallograph...

Believe in your own ears and listen.... One experiment after the other....

My best to all....

For me, they work. Significantly.  I place them vertically on my 2A3 tube amps between the power and output transformers. Everywhere else (DAC, SS amp, preamp, transport, music server) not at all.

Those are the only tweaks I use.

I have used them to great effect with CD/SACD PLAYER (over the transport and Power supply), and also on the amplifier CODA CSX (over the toroidal transformer). The presentation became more open, relaxed and the noise floor was lowered to an inky black. YMMV. 

I purchased a Shakti stone last year. It’s effect was immediately apparent and 100% repeatable on each piece of equipment I placed it on including the main breaker panel in my house. As the instructions stated the effect of the stone depends on its orientation on each component. If you don’t hear a change in sound rotate the stone 90 degrees, again, the effect was 100% repeatable each time. As for the sound, it produced a darker background and made the soundstage bigger. However, the larger soundstage was ‘artificial’, instruments went from sounding life size to being too large, the singers voice was exaggerated so their mouth was like a foot wide. I liken it to increasing the size of a picture in MSpaint, when you stretch it out it becomes larger but all the pixels become blocky. I did not find it pleasing in my system due to the exaggerated, no longer life size scale of the music. Perhaps a different system could benefit from the use of a shakti stone.

About as effective as Shun Mook Pucks, Geoff Kiat’s Pebbles (https://www.machinadynamica.com/mikro-pebbles.jpg), $150 Boutique Fuses, HFT’s and a host of other snake oil products, that convince the gullible to hand over their cash.
