Quantum dots. Matter waves. Photon bombs. Artificial atoms. The Intelligent Chip by Golden Sound stirred up these and related terms in recent debates to hypothesize and hypnotize on how it works. Our jury is still out on whether it even works. Our first team of writers heard absolutely nothing with multiple transports/CDPs. They also alerted me that a high-tech lab specializing in fabricating machines which then produce chip wavers applied advanced microscopy to their sample chip. They found nothing but a piece of PCB and one applied dot. Calling this dot a quantum dot can be cavalier. When the Greeks coined the term atom, they theorized about indivisible particles making up matter. As the terrible events of Hiroshima and Nagasaki proved, indivisible can be a function of magnifying power and applied technologies. Quantum mechanics and string theory deal with subatomic particles and their apparently random, logic-defying behavior. From that perspective, everything material that is composed of atoms is also quantum. Singling out one metallic dot as though it were endowed with magical properties could be a dead-end alley.

Quantum Resonance Technology or QRT is a Santa Monica/CA firm which purportedly applies Quantum Physic theories on electron propagation to audio/video power devices. The Symphony Pro is a parallel device. It simply plugs into the AC line to release a "subatomic signal" activated by an oscillator/transmitter. This pulse or dither is broadcast by a small electromagnetic field generated by an RF detection coil and propagates across the power line. This pulse also acts as a "wireless electromagnetic field stabilizer up to a range of 50 feet or a room of 30' x 50' ". The Symphony Pro is thus dubbed an electromagnetic field conditioner said to be effective in conjunction with other noise suppression or line conditioning approaches. At 5.5" W x 5" D x 1.5" H and 2 lbs, the Symphony Pro is a lightweight dwarf with a glass-covered blue LED upfront and a power IEC and mains switch on the rear. Quantum claims "increased periodic S/N ratio by 15% when installed into an audio signal transduction network."

Further explanations on the workings of this device include the following: "A sea of electromagnetic fields (EMF) from electrical devices, power lines, computers and wireless signals results in thousands of EMF frequencies containing many billions of electrostatic charged particles disrupting the signal path of every component in any high-end audio/home theater entertainment system. Like a magnet aligning iron filings, the Quantum coherent polarizing field effect "aligns" charged particles associated with EMF frequencies. The resulting coherent field enhances the signal path allowing greater audio/video fidelity." Elsewhere, the QRT treatment is said to "enhance the transfer function of conductive materials" and the effective range of QRT's own Symphony device is claimed to extend in a 35' omnidirectional radius (sphere) around the unit." [Note how EMF fields here are viewed as particle waves - Ed.]

QRT is also found inside such components as Kiuchi-San's ALS-777 Reimyo power line conditioner under the Combak/Harmonix flag and Lloyd Walker's Velocitor S. Unlike the mysterious Intelligent Chip, this technology actually employs definitive material components that don't require microscopes or nano-technology mysticism to - um, see. Lloyd Walker doesn't profess to fully understand how QRT works but like Kiuchi-San, his ears tell him that it does and his tweaker's nature has shown him how to improve and optimize the basic technology. Considering the parts quality and execution of the Symphony Pro, it's obvious why Walker Audio rebuilds the modules.

Incidentally, the notorious Bybee devices are based on and explained via very similar technology and terminology. In layman's terms, I've been told that while electricity propagates at nearly light speed, individual electrons move far more slowly. They actually create bumper-car traffic noise while passing through the crystal lattices of conductors. Both QRT and Bybee devices are said to align or orient this electron flow. This supposedly minimizes propagation noise. It also accelerates current flow due to more optimized and thus faster electron movement. Walker's clever name of Velocitor i.e. accelerator seems very canny in this context.

With Chinese-sourced parts and plainly cost-conscious execution, the opened Symphony Pro displayed a 5-volt switching power supply with slip-on connectors, the afore-mentioned coil embedded in a 'pulse block' and said contraption itself attached to the power supply and a board-mounted chip which presumably acts as the oscillator microprocessor. Like Walker with his latest S-version Velocitor, QRT's Bill Stierhout has recently applied an active bias to the detection coil that's sourced from the power supply.

Many power conditioner makers including Walker and Sound Application rely on visual feedback (exclusively so or to augment and confirm auditory perception) via television monitors. Audible differences translate to visual ones. Most would agree that with subtleties, eyes tend to agree far more with other eyes than ears with ears. Still the beneficiary of Bel Canto's phenomenal PLayer loaner, I headed straight for our 2-channel video rig and plugged the Symphony Pro into the BPT BP-3.5 Signature Plus currently residing there.



My wife is a painter and has the exceptional sence of color. It took her no time at all to pronounce the QRT effect visible in how color-base detail and texture deepened. We used period movies like Girl with a Pearl Earring and Age of Innocence for their opulence of textiles and paintings and the opening of Art of War for its sheer intensity of colors during the Millennium Celebration and subsequent aerial escape. I had to agree. Color saturation and haze-free clarity had clearly jumped up a notch. A wooden doorway with sun-faded paint showed off more grain texture in the wood and a higher numbers of hues in the paint. Woven fabrics displayed dye irregularities and a sharper relief of surface patterns created by the threads. The Chinese balloons popped louder with their bright hues. Would what our eyes so clearly agreed on without deliberation, effort or second-guessing translate to the big rig?

In two words? No but. Despite the claimed field effect and reach of this technology, the Symphony Pro added something significant enough 17' and 24' removed from two plugged-in transmitting Walker Audio Velocitors to become visible in our television corner. Alas, plugging the Symphony into the very system already employing two QRT modules by way of the Walker units didn't add anything I could discern. This leads me to two conclusions. A/ Despite the cited 35 -50' reach for the QRT field or dither signal, proximity plays a far greater role than the claims would suggest. B/ Stacked QRT via multiple units and in the same system isn't necessarily additive enough to become audible.


Does QRT work? Quantumfiably so. Is it earth-shattering? As implemented here? I first thought no. Would I spend $500 on the Symphony Pro? In a video system of the PLayer's and Sony's resolution that visibly benefits, certainly - though comparing a $500 television to what's inside this box makes the latter seem unnecessarily expensive. But that's true for most of HighEnd audio. How about in a 2-channel system like mine above? There I couldn't say since I'm already QRT'd to the hilt. I have no way of knowing how much the quantum modules inside the Velocitors contribute to their overall performance and how much the remainder of Walker's address. Unlike with the Symphony Pro, you cannot turn off the QRT portion of the Velocitor to compare. For audio evaluations, I used the video system anchored by my new Zu Cable Druids run off Nelson Pass' phenomenal FirstWatt F1 10wpc current-source amp.
