Shakti On-Lines are $100 "electromagnetic stabilizers" that you place upon cables in your audio setup. They join "THE STONE", a $229 item that the user "need only place in close proximity to his component's power supplies and other critical circuit locations to realize audible sonic benefits."
But that's not all! They also have your DVD player covered, promising "reduced color noise and improved convergence alignment" among the improvements that can occur.
Also, your car's horsepower.
Placed near automotive CPU's, the On-Lines have demonstrated the same horsepower improvements as the Stabilizer. In some applications even closer proximity to chips is realized.
Skeptics should note that reviewers Clay Swartz and Karen Wong independently tested them and vouch for their efficacy.
Another interesting effect of the Stones was noted on playing a Blu-ray disc. I had asked one of the audiophiles to bring his copy of the Blu-Ray of The Last Waltz. I had watched his copy about a month before. When I got my copy, I played it and thought it was better than his copy. I played my copy and he agreed that it was a lot better than his. Next we played his copy and there was not much difference, thus we learned that the Stones can enhance playback of Blu-Ray discs.
Here's Stereophile magazine:
Focus, transparency, clarity and speed were better, as was the sense of space and pace. It's not that the SHAKTI improved the amps so much as, they allowed them to perform to their fullest. Used intelligently and in the right places, the SHAKTI offers a worthwhile and cost effective boost in sound quality.
Likewise, one Stephen Harrell reports that he is "hooked on the liquidity and persuasive presence they coax from the string of boxes in my system". Jonathan Vallin of Absolute Sound cautions, however, that the stones must be "used sensibly".
If you've read this far, you may well be ready for The Hallograph Soundfield Optimizer, which "contours the frequency, amplitude and time coefficients of the first reflections you hear, which produces a stunning increase in realism."
They're wavy, see, just like sound waves.
