Shakti Stone?

david99: my advice is to place the shakti in a pre-heated 300 deg. oven for 30 minutes, then with mittened hands put it under the foot-end of your covers when abed you go on a three dog night. on a slightly more serious note: the presumed effect of the stone is more likely to be perceived on your pass than balanced atop the rouge's power supply.

I use 3 stones- one of them on top of DAC area of CD player- noticable results- slightly smoother, hair less grain, etc. (guess its reducing digital 'hash' etc.). Second stone is on top of DCS Purcell upsampler, and third is on top of A/V processor. I tried on top of tube preamp, but not as much effect. Overall, I highly recommend. Hey, whatever its doing- works for me!

Of course it all depends and the design and existing EMF shielding of each component. I have played with stones on various pieces, easy to test just listen with and without, and I feel they don't make a noticable improvement. As a matter of fact I could detect no real difference in sound. But with any tweak item, different systems may produce different results. My epuipment is all Musical Fidelity SS, Bel Canto Dac1.
