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?

The main important first knowledge fact in audio life is this one, some of us learned the hard way:


Past some point in technological electronic engineering improvement in the past collective or personal history, the main improvement coming from an audio system, come less from an electronical design new progress than from an improved control of the mechanical, electrical and acoustical embeddings of the audio system...


Most embeddings controls are often simple devices and also sometimes simple advices (speakers positioning) and play now the first role in the increasing of the S.Q. of an audio system...


The devices i created for myself cost peanuts and worked so much that they transform my basic vintage good audio system to a new level ...


Anybody can make them, anybody can create better device at low costs....


Knowing that it is not so much buying better gear, past some point of your purchasing history, that will improve your system, the so called "upgrading process", but the increasing controls of the mechanical electrical, and acoustical dimensions is the most important basic fact in audio life...


Dont upgrade anything before embedding everything rightfully....

This is the basic axiom of audio....

And the ONLY important knowledge for most of us, engineers or not.....
@mahgister-    I've always held that the first three letters of, "assumptions", described those that make them.       The cult of the Naysayer Doctrine, wants you to accept their revelations, by faith (ie: YOUR senses and mental faculties are worthless and deceitful).    You MUST follow their precepts, or- be eternally DAMNED to partake of their (seemingly) inexhaustible fountain of ubiquitous, misinformed/uneducated, faith-based, hubris-salted, BLATHER.     Well: at least until they manage to get a thread removed, through their antagonistic barking (salvation preaching, no doubt, to their fevered, tormented minds).

This is absolutely true and it's one of the great ironies in audio. Many of those who would proclaim themselves "objectivists" are actually those consumed by a faith-based belief system. That's why they can so readily reject observations that aren't consistent with their beliefs. It is the very nature of faith; it requires no proof. 

Empirical evidence is just an inconvenience to the measurementalists, who seek comfort and security in their faith. And just like some religious fundamentalists, the measurementalists can be tireless in their evangelical proselytizing.
Exactly!      Far as, "harm": the incessant, unfortunate presentation of their beliefs as categorical imperative, or- TRUTH, rather than as the misinformed, uneducated and (largely) untested OPINIONS they are, is what I believe contrary to (what used to be) the spirit of this website.      The thought that they could succeed in dissuading a new audio enthusiast from experimenting for themselves (regardless of the topic or component) and being robbed of potential listening pleasure, is what dismays me.

At the risk of splitting hairs with you, @rodman99999 it is actually much worse than that. Not only do the measurementalists discourage experimentation, but they will dismiss wholesale the result. Check out this thread:

No, you think it sounds better to you. That is completely meaningless to other people
Even the report of a sonic preference can be dismissed with the wave of the hand. Which prompts the question: Of what value is this website if we can’t report our experiences and preferences?
