Shakti Stone

From - The Stone Operation by Bosch.

 I tried them years ago. They don’t do a thing. What does work are Synergistic Research Tranquility Pods. I now have 5 in my system.  You can get a free in home audition through a Synergistic dealer which I did.

@tablejockey , I appreciate your fair warning and as a DIY guy, I grow most of the stash I smoke. 

Vast majority I only grow from seeds and never clone any species. 

Even given that, today in the 21st century you can get ALL kinds of stones Indica, Sativa, Hybrid and maybe Shakti too.

Only pet rocks will work.  So before you try them, talk sweet to them and you will be rewarded.

I find that the best stone to dramatically improve soundstage is my grower son’s Banana Daddy Hybrid.  Amazing increase in the depth of the soundstage and holographic.  Best and cheapest upgrade to my system yet!
