Shakti Stones Do they actuall work guys.

Yes they work. I would start with one directly on top of your amps transformer. I have not had any luck (good or bad) with them when used with digital equipment. I have one on the transfrormer cover inside my Classe CA400 amp. (major improvement) I had two on my ARC Ref 1 directly over the power supply transformers. (not as dramatic as with my amp) I moved the stones to the tops of the first network boxes on my MIT 850 Ref speaker cables. (substantial improvement) I have started to experiment with the On Lines, so I'm still working through the learning curve with these. The stones lifted a layer of grunge that I didn't know existed. More "air" and detail in the music. There is one area were they made things worse. I tried a stone inside my Martin CLS electronic boxes and an On Line on the ESL panel leads. The sound just became congested and lifeless. I hope this info helps.
