TAD POWER PURIFIER DESIGNED BY BYBEE

Sign In to see what this sold for

REVIEW: TAD Systems of San Mateo has sent a me a new product for evaluation, called the "Power Purifier." Catchy name... pretty much self explanatory. Designed by Physicist Jack Bybee, this baby borderlines on the exotic.The Purifier measures 15-3/4" wide x 3-7/8" tall x 6-5/8" deep, and is a hefty little thang. The front is plain Jane, with only their name plate showing. The rear panel has two removable power cords; one for the block of eight low amperage outlets (sources), and one for the block of four high amperage outlets (amplifiers). The two circuits are separated internally from each other, and the entire unit operates passively; merely passing the signal through it, without any further electronics involved.Opening up the unit doesn't do a whole lot to demystify the Power Purifier. Each block of outlets are wired in series amongst themselves with solid copper wire, and then tapped off the last outlet with stranded. The power cord wires are also stranded. Now, here's where we crank up the theme from the "Twilight Zone", and things get a little different than the rest of the pack. The wires of the power cord enter two blocks-o-mass (one for sources, and one for amps) , and exit on their other ends to head to their respective outlets. Inside these blocks, is where the work really gets done. The potted devices inside are fabricated from ceramics containing rare earth metals such as Zirconium, Yttrium, Neodymium, Praeseadoyium, and Lanthanum oxides. It is the combination of these materials, which are very expensive and have only been used by the military, that create a barrier to isolate, block, and absorb specific electrons that create distortions in the audio signal.The Power Purifier utilizes technology based on extensive research into the principles and materials relating to superconductivity. Renowned high-end designer John Curl offers his comments on the Power Purifier. "There may be other AC line filter systems that filter in the same frequency range, but the Bybee filter design does not use any caps or inductors, so the source remains resistive (.05 ohm-.3 ohm, depending on filter); this seems to be a big advantage. The Quantum filter does not eliminate line harmonics, and is not a super RFI filter...It does filter noise that would pass through most RFI filters." Curl is hoping to make a small version of the unit as a mod for his Vendetta phono preamp. "I have to keep improving the power supply system to keep up with other designs, or I must (use) battery power to get optimum. The Quantum filter helps me retain high current capability of AC line operation, rather than compromise with battery operation."The Power Purifier is designed to operate over a limited range, just below where good RFI filters cut in; so don't expect this product to take care of any unwanted RFI problems. The use of an RFI filter ahead of the Purifier, or ferrite clamps, Red Rollers, etc., may still prove valid in conjunction with this product. I plan on examining this in the next few months, and will report the results. The Purifier also will not solve any ground loop problems you may have within the racetrack of cables and components downstream. If you still hear any 60hz. hum in your system with the Power Purifier on line, it's a safe bet it's coming from something else. It has been measured (by the designer-you know I'm not sharp enough to do such a thing) to reduce jitter in digital clocks; and is said that this may be the reason that it works so well with digital processors.TAD Systems lists these reasons how Quantum Purification differs from other power conditioning products on the market:The Power Purifier contains no filters or notch filters than can cause phase shifting.No Isolation Transformers that allow trans mode noise to pass. Even though ISO source impedance is low, they can also contribute to constriction.No Ferro Resonance devices that have high source impedance (z) and can create excessive heat.No transit voltage surge supressors that add excessive impedance and additional noise due to capacitors and MOV's....Dave Duvall... available for preview in Charleston SC, call 260-418-6576 or email sales@estateroadshow.com
