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.
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?
