My wife affectionately calls me "Tweakman." I am a passionate advocate of the many benefits that happen when you tweak a room and/or a component. Tweaking can create huge sonic improvements on an audio system - regardless of its price or performance.

My quest for new approaches to extract more musicality from my audio system led me to a collaboration with my friend Ben Piazza and resulted in our co-invention of the Shakti Hallograph. This powerful passive room tuning device helps create a wider, deeper, more natural and musical soundstage. It's very success tells the story (15 years and counting). In the beginning, Ben and I would go to CES and do live demos with a pair of the Hallographs, putting them up and down without stopping the recording. Most people were amazed at how powerful a transformation we made with our device. They just made everything come to life with more musicality.

Back to the Future....  

I  remember the day my buddy Clement Perry showed up at my house and insisted I try a pair of Jack Bybees’ Golden Goddess Speaker Bullets he showed me. I hooked them up to my Apogee Stages' speaker terminals and listened. Everything sounded very different and it left me unsettled. I took them out of the system and listened again. Then I put them back in and I knew I could never live without them. They just made the music sound more natural. They pulled out noise I had assumed was mainly coming from sub-par CDs.

I realized that tweaking my audio system would be a long ongoing process to properly deal with the insidious noises that continue to undermine its performance. It was chockfull of resisters and capacitors, circuit boards all hooked up with long runs of speaker wire, interconnects and AC powercords necessary for turning  the endless stream of electrons into the music radiating out of my loudspeakers. Unfortunately, the very circuits and long runs of wire that make everything work, also act like giant antennas, pulling in various types of distortions. The circuit boards themselves are also generating fields that create their own noise. These contaminating fields can prevent any system from reaching its full potential, no matter how well components and speakers are designed and engineered. A  good AC conditioner is  important but  it doesn’t completely deal with all the issues. A power conditioner is a good step forward but it’s just the first step.



Jack Bybees’ latest invention, the subject of this review, the Bybee Quantum Signal Enhancer is able to neutralize and further reduce the noise elements in your system and increase dynamics and make the music just sound better. The great thing about them is that you can place them almost anywhere in your system - on speaker cables, interconnects, under amps, DACS, on loudspeaker crossovers and just about any place in your  audio system.

Bybee Quantum Signal Enhancers (herein Enhancers) are thin, lightweight and extremely powerful. Measuring a mere 4”x6” long, 1/8th" thick and finished in a shiny black lucite. Embedded inside the Enhancers however is Jack Bybee's remarkable new Crystal Technology (the same technology used in his and exciting AC powercord reviewed). Russell Lichter goes great length in an attempt to explain the Crystal Technology in his excellent review of the Bybee Crystal AC powercord (here).

Jack Bybee’s background in quantum physics enables him  to solve problems in a unique way and create devices that truly push the boundaries in audio noise reduction technology. I decided to add these Enhancers one at a time to my system which was already tweaked out with an arsenal of devices like the Stein Harmonizers, Novum Resonators, IPC Energizers, Shakti Stones and Hallographs, Bybee Speaker Bullets and more. I chose to begin my experiment with 5 Enhancers which I felt was a reasonable number and would show their capabilities.

I put my first Bybee Enhancer under my PS Audio DSD DAC. The Enhancer created a noticeable  improvement to the sound that went way beyond its $119 asking price. I put the second one under my Wells Audio Innamorata stereo amplifier. And again, I heard an increase in musicality and image clarity with less grain and more natural harmonics.

I placed the third Enhancer under my Bybee AC Conditioner. This particular placement seemed to provide - what is already an extremely good conditioner - even better dynamics and resolution. Excited, I placed the 4th and 5th Enhancers one under my speaker cables and this resulted in an overall quieter and musical presentation. All this for $599! I would certainly qualify this a bargain!

I decided  to test the 5 enhancers on my friends system which is much less tweaked out than mine. We placed the first  one under his Sim Audio Moon stereo amplifier and sat down to listen. We both felt it took some noise out of the system while providing slightly greater depth to the music. He remarked that it was  not a dramatic improvement but  it was certainly a bargain for the results we achieved with just one Enhancer. The 2nd one went under his PS Audio PWD DAC.

Now things were getting interesting!

dianakrallgirl.jpgWe listened to Diana Krall’s  “Girl in the Other Room” CD. Her voice became more dimensional, then we put in the 3rd and 4th Enhancers against the crossover networks of his Apogee Duetta loudspeakers.  We were both wowed by the increase in soundstage depth and the overall naturalness that enveloped Diana Krall's  voice.  It was as though a veil had been lifted. A 5th enhancer went  under his Audio Research Preamp and this addition took the system up another noticeable notch. The improved sense of quiet gave greater contrasts and of course this lent to greater dynamics  and still further clarity. Once situated with all five Enhancers in his system, my friend was impressed beyond measure that these small,  light-weight and inexpensive devices could make such an improvement to his system.  Of course, like all of us, he was heartbroken when I had to take them home with me (of course, he hurriedly ordered a replacement).

The beauty of the Bybee Quantum Signal Enhancers  is that they work almost anywhere you put them in your system. And they're affordable! The remarkable improvements they make can be used to enhance your system whether modest or  state of the art. I highly recommend the Jack Bybee Quantum Signal Enhancers.

    Hi how do the Bybee quantum enhancers compare to the Shakti stones?


    That's a good question Ked,
    I've not compared them side by side since the Shakti Stones are, shall I say, "old school." BUT, I would think the Bybee Enhancers would be as effective - if not slightly better - at half the price. Can't beat that!

    This item need power in? If yes, 110V/220V?

      If we read it, it says no need power in.

    Do they make a metric version?This one appears to be US.

    Hi Mel,
    Don't know what you mean by a metric version. Can you further explain?

    Only by belief

    Hi Mark,
    Not going to argue with you except to say you might give them a listen FIRST. Then say they do not work.

    Are they bi-directional? Does it matter whether they are under or over the equipment? Is there a break-in period?

    Hi Jack,
    I've asked Jack Bybee the same question and the answer is: YES. They are designed to be placed either on the top or the bottom of your component using the shiny side. As long as the shiny side is making contact you're good according to Bybee.
    Thanks for writing

    If this was 'novel' it the creator would have patented it. If it was even remotely true, at the very least a patent would be pending. You are selling an aluminum pad for $119 dollars, shame on you. You have offered no schematics, data, or any common sense as to why it 'works'. Classic snake oil salesman tactics "IT WORKS! TRY IT! BUY IT! MY FRIEND HERE, SMART GUY, SAYS IT WORKS!"

    I am a "scientist" (M.Sci in Physics) and I would just like to add that all of you have been robbed by this Bybee guy. His explanations use wording intentionally designed to confuse, and many explanations contradict themselves. This is a simple explanation to why this, and all of his products are pure "snake oil"; There is no such thing as a "signal purifier". Adding anything to the signal path will only distort or modify the signal, not purify it. Only the device emitting the signal can emit a cleaner signal. Any distortion picked up along the signal path (mostly mains voltage ground loops and problems due to improper isolation/dielectric/insulation) can be fixed by REMOVING THE SOURCE OF THE DISTORTION! "IF" this thing works, its because it simply lifts your mains voltage supplying power-bar off the floor, which is a common recording engineer trick to remove ground-loop hum in microphones and other audio inputs.

    "Quantum Noise" is not audible, never has been, never will be. It operates on such high and low frequency that it is WELL beyond human perception. All matter resonates, It just resonates on a "quantum level" that is NOT PERCEIVABLE by humans without electronic aid and then only on a computer screen as data. We have deep-space telescopes that operate on microwave frequency, we cannot see, hear, or feel those microwaves, because they operate outside our perceptive abilities as humans.

    Hope none of you bought this junk, like the user said above, if this device was anything unique or "novel" (scientific term) he would have a patent on it. If he is a scientist that is the FIRST thing he would have applied for. At the very least he would have a patent pending (which is likely to fail) He gives no information on what materials this device is made of, or any schematics. The only scientists that don't offer these things are quacks or thieves.

    If you don't believe me take a trip down to your local university and find a physics professor in his office or sit in on a lecture to ask a question after. Professors love to disprove "quack" scientists and scammers who are using their knowledge to rip off customers. Most professors offer their services willingly for members of the public and concerned citizens. Don't be afraid to ask a professor (I am not a prof. and I work in private industry)


    Sorry Professor Johnson, but the more I listen the more I like what the effects are, even if they're just altering the sound as you presume. Problem is, I like the way the Bybees alter the sound. Period. I'm no technical wizard and you're probably not a music lover/audiophile. Because if you were, you wouldn't argue the improvements I and so many others have heard over the years.
