The new improved Shakti Stone Air! The first modification to the Stone in over 20 years! Even more audible benefits when placed on components comparied to the original.Shakti Stone's proven capacity to reduce EMI is much greater, giving the listener a cleaner, more musically accurate playback!The SHAKTI Electromagnetic Stabilizer (aka "the Stone") has three internal trap circuits (Microwave, RF and Electric Field) to absorb the broadest spectrum of EMI. Placement on automotive CPUs has measurably increased engine horsepower. It also improves resolution for virtually all-major components in high definition audio/video systems. Music reproduction is clearer, with more liquidity, dynamics and focus. The improved inter-transient silence allows the listener to hear ambient cue information essential for accurate perception of stage depth, width and unwavering imaging. High quality video systems will benefit from SHAKTI devices near power supplies, projection guns and laser disc/DVD players. Reduced color noise and improved convergence alignment are some of the improvements that can occur. In automotive applications, where space allows, the unit should be securely taped and/or cable tied to the top of the CPU.The Shakti Stone is an electromagnetic stabilizer that requires NO electrical hook-up. Simply placing the Shakti on a component results in instruments and vocals that are clearer and sweeter, with more liquidity, inner detail and focus. The imaging, stage depth and sound stage depth are more accurately replicated with the original recording site."Just when I was getting to feel that I would not have to add any more tweaks to my system, in comes the tweak that has caused the greatest improvement in sound of any tweak that I have ever tried in my system. The noise floor was substantially improved. Tonality and timbre were improved. There was more sense of air between instruments. In short, recordings became more musical, and I found my enjoyment of that music substantially improved. SHAKTI is not only highly recommended, but I consider it utterly necessary if you wish to get the most out of your system." - Clay Swartz, Positive Feedback, Vol. 5 No. 4, 1995"Suddenly, something was very different. First of all, the background darkened. Whereas previously it was sort of grayish-black, so that some low-level detail had tended to merge with it, now it was completely black. The music was set off against this blackness, throwing almost everything into sharper relief. Resolution was heightened, and because I could hear greater detail, the music took on a more rhythmic, more emotionally charged quality. I didn't think that adding one more stone anywhere else would make any kind of difference. I put the stone on the center of my CD player, and played the same track. Lo and behold, I was transported to yet another dimension of resolution. I suppose the best way to summarize the most beneficial effects of the SHAKTI Stones is to say that they added smoothness to my system. All the brashness associated with digital equipment was taken away, making the end result very easy on the ear, and a generally much more relaxing experience." - Stephen Yan, Audio Video Singapore, November 1995"It seemed to sharpen the focus and quiet the background, heightening the sense of imaging… 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." - Jonathan Scull, Stereophile, February 1996"Leaving the volume control untouched, I took one of the SHAKTI Stones, placed it square on top of the JVCXLZ-11-TN CD player, and played "Famous Blue Raincoat" again. I'll be damned if there wasn't a whole new level of depth and clarity to the presentation. Pretty amazing. From the midrange on up, everything sounded cleaner, that cool-breeze-after-a-hard-rain kind of cleaner. The low level high frequency grunge to which I had adapted, "This is as good as this system is gonna sound in this room" was noticeably diminished. I repeated the experiment with "Revolution" and "Someday Soon" (and with plenty of other music since) and found that the effect was repeatable and verifiable. I've tried it on other folks and they've heard it too. Jonathan Scull's endorsement in Stereophile February 96 (vol.19 No. 2, p. 177) was right on the mark. I give the SHAKTI Electromagnetic Stabilizer a big "thumbs up."" - Barry Willis, Stereophile, April 1996"Used sensibly, the SHAKTI Stones clarify inner details (particularly delicate harmonic and dynamic details), reduce inter transient noise components and grain, increase transparency, markedly improve focus, and simply produce a more realistic sound than non-SHAKTI’d components… On large orchestral recordings, this reduction of grain, increase in dimensionality, and tightening of focus markedly increase transparency, allowing a clearer view into the stage… The SHAKTIs make such a marked improvement that they should be considered an essential tweak." - Jonathan Vallin, The Absolute Sound, May/June 1996"To recap, SHAKTI Electromagnetic Stabilizers are placed on top of transformers, speakers, etc. like a VPI brick or Flux Dumper. Internal circuitry'yup, passive internal components' is supposed to work all sorts of groovy magic; and I've witnessed convincing demonstrations on speakers and valve amps too many times to dismiss them. (Confession: I use the Stones all the time, I just don't boast about it). What doesn't need sorting are the On-Lines themselves, which clean up the sound in a manner reminiscent of Simba clamps." - Ken Kessler, Hi Fi News and Record Review, August 1997"I don't know what the specifics are, but the thing really works. There is an obvious reduction of the noise floor, which rather significantly improves the sense of dimensionality, and the dynamic impact, of individual instruments. The presentation becomes cleaner and more liquid without losing detail of focus. Indeed soundstage dimensions are better delineated. Very appealing!" - Lars Fredel, Fi Magazine, Jan-Feb 1997Dimensions:6.5" L x 5.25" W x 1.5" HWeight:1.275 lbs
