Are Shakti Stones effective?

+1 @artargyle

I used many materials, trying to damp vibrations over the years,(years ago). Yes I could here differences. Realized later, that as far as controlling vibrations goes, starting from the ground up made more improvement and more sense.

These devices like Shakti, Bybee, Akiko and so on aren't the same. Just because Shakti is placed on top of a component doesn't mean it's purpose is mass loading.

If the weight of a stone reduces vibrations in an audible way then great. As far as hearing a different soundstage or "inkier" backgrounds, sure-- you might hear them, you might not, either way it's more likely you and not the stones. You have adjusted your focus-- and when your ears try to hear something differently they just do-- even when nothing has actually changed audibly. You sip a wine, someone points out a flavor note in it you hadn't noticed, and suddenly there it is-- and there it always was. So much snake oil, so little time...

I guess the same could be said for those that refuse to believe.
