2013 Rocky Mountain Audio Fest Introduction
The Synergistic Research High Frequency Transducer (HFT) and Frequency Equalizer (FEQ) are two new products that were recently introduced at the 2013 Rocky Mountain Audio Fest in Denver (see show report). Synergistic Research decided to make a not-so-subtle point by using a Bose Wave Radio placed on a Tranquility Base to demonstrate these new products. Ted Denny III, Lead Designer at Synergistic Research, wanted no confusion that might occur using a high end audio system. Ted felt that if his new products could transform the sound of a Bose Wave Radio, a true high end audio system would experience even greater benefits from these products.

My original intentions for the use of these products were in the application of computer audio. But as I discovered, the HFT and FEQ go far beyond computer audio, and benefit all audio systems regardless of their source. I felt that these new products were so significant in their performance that I should share my total experience with the AudioStream readers. So please indulge my deviation from computer audio as I describe the HFT and FEQ products.

The High Frequency Transducers
The High Frequency Transducers are very small aluminum cylindrical objects with an inverted cone at their tops. The HFT measures a mere 8 mm in diameter and 8 mm in length. Using a little Blu Tack at the end of the HFT allows it to be attached to a wall, cables, etc. These devices are passive and require no active power supply. The HFT are sold in packages of 5 for $299 or $75 individually. Synergistic Research makes a bold statement that the HFT improves all aspects of system performance.

Peter Hansen, Vice President of Marketing at Synergistic Research, came to my home to demonstrate the HFTs. He began by placing 2 HFTs on the rear wall in each corner, and 1 in the middle of the rear listening wall. I was really startled by what I heard after he placed these tiny objects on my wall.

The soundstage became larger not only in width and depth, but also in height. The bass seemed to be a little better controlled with enhanced clarity to the sound of vocalists and instruments. Now this effect was obtained with only 5 HFTs. Peter next placed a total of 5 HFTs on each of my Wilson Sasha speakers. 5 More were placed on each side of my Wilson Watch Dog II subwoofer. The sonic results that I previously described were now magnified with the addition of an improvement in the noise floor. An HFT was then added to each side wall, the lower portions of the front and back walls, and an additional HFT in the middle of the back wall. Midrange clarity, high end definition, soundstage, bass definition, and perceived noise floor all improved.

Peter then suggested that we try the HFTs on my digital cables. We placed one on each of my Synergistic Research Active SE Thunderbolt cables and an Apple Thunderbolt cable. I’ll be damned if I didn’t hear an additional improvement in the sound of my system. The sonic effect of the HFTs in no way exaggerates the soundstage or brightens the sound. As you listen to these devices, everything just sounds clearer and more natural. But we are just getting started; enter the Frequency Equalizer.

The Frequency Equalizer
The Frequency Equalizer physically is a black rectangular object with aluminum top and bottom plates. It is a small black device measuring 7.25 inches in height and 4.125 inches in width and depth. There is an on-off switch on the back of the FEQ with two receptacles; one for a ground plug and the other for a wall wart power supply that is pretty hefty in weight. A blue LED is illuminated on the back of the unit when the FEQ is on. Synergistic Research feels that the FEQ acts as a Tranquility Base for the room enhancing the total sound of your system. The ground plane technology found in the Synergistic Research Tranquility Base and PowerCell products are utilized in the FEQ. As with the HFT, the concurrent use of the FEQ provides similar system enhancements but even more striking and pronounced than those achieved with just the HFTs.

The Sound Became Holographic In My Listening Room
The FEQ’s sonic effect when on is very obvious; especially when used concurrently with the HFTs. The soundstage became even more layered in front-to-back information with superior reproduction of the acoustic space and air of the recording. Soundstage height became larger and more natural sounding with less constriction of the music. The best way to describe this phenomenon is that the soundstage seemed holographic in its presentation. The FEQ seems to remove a dark veil from the music with superior rendition of high end detail and transients. Vocalists and instruments were more vivid and easily heard with the FEQ on. Bass was much better defined and had more impact. The FEQ’s effects were not subtle. Turning the unit on and off allowed me to easily asses the sonic contributions of this component to my system. The background silence was improved as it was with the HFT, but even more so.

I then placed an HFT on my USB cable connector from the computer. Without the FEQ, I didn’t notice much of a difference using the Synergistic Research Active SE USB cable or the Light Harmonic LightSpeed. But with the FEQ, the use of an HFT on the USB cable resulted in a subtle, but noticeable improvement to the sound.

A Reduction of Grain
Another additional benefit of the HFTs and FEQ when paired is the reduction of sonic haze or grain in the musical presentation. One recording that I especially enjoy is the native DSD Blue Coast Records recording of Jenna Mammina Special Event 30. While I have always liked this recording, I have found a subtle hardness to the sound. With The HFTs and FEQ, that grain or hardness was removed. I found that my listening was more relaxed and enjoyable with the HFTs and FEQ.

A similar finding was observed with Eiji Oue / Minnesota Orchestra playing Exotic Dances from the Opera (Reference Recordings HRx 24/176.4). While this recording has a magnificent sonic stage and explosive dynamic qualities, I always felt that it was a little hard and dry sounding. The HFTs and FEQ removed these issues from my system and replaced it with enhanced sonic textures and image specificity-focus.

Cecilia Bartoli with I Barocchisti and chorus of R Si Lugano performing the Steffani Stabat Mater (Hdtracks 24/96) greatly benefited from the use of the FEQ in my system. Not only was Bartoli’s voice better delineated and focused, but the acoustics of the recording venue were more easily heard and were much larger in soundstage width, depth and height. The exceptional rich texture of I Barocchisti’s period instruments along with Bartoli’s voice were beautifully displayed with the FEQ and HFTs. The voices of the chorus and instruments seemed to collapse into a congealed relatively opaque space when the FEQ was turned off. Complex recordings of instruments with vocalists and chorus such as this one easily displayed the capabilities of the HFT with the FEQ.

I then listened to R.E.M. New Adventures in Hi-Fi 48/24 (Ripped DVD-A) opening track. This cut has a strong bass line and I was interested to see how the HFTs and FEQ handled this music. With the HFTs and FEQ the bass was well defined, impactful and very dynamic sounding. Turning the FEQ off resulted in a soft, somewhat ill-defined bass and a collapse of the soundstage. The punch of the bass was lost.

The PowerCell and Tranquility Base
For those of you that own the latest PowerCell line conditioners and or Tranquility Base, these products will give you a feel for what the HFT and FEQ products do for the music. The ground plane technology in the new PowerCells and Tranquility Base is implemented in the active Frequency Equalizer. In fact, Ted told me that the effect of the HFTs and FEQ are even greater when used with these products, although it is not necessary to own a PowerCell or Tranquility Base to enjoy the sonic benefits of the HFT and FEQ. The FEQ’s sound can also be slightly improved by placing 3 of Synergistic Research’s MIG footers under the base of the FEQ. The MIGs should be placed convex side up for best results.

The next experiment I wanted to try was to see if the FEQ’s sound could be improved plugging the wall wart power supply into a PowerCell 6SE power conditioner. In my setup, the PowerCell 6 SE is plugged into the PowerCell 10 SE MK III for physical extension purposes. The FEQ definitely sounded better plugged into the PowerCell 6 SE conditioner. It sounded a little bigger and more open sounding with a lighter and quicker texture to the sound. Also there was a bit more presence in the midrange. But the sound of the FEQ plugged directly into the wall was still excellent. I wouldn’t worry about not having a PowerCell if you don’t own one. It’s just that in my experience with these products, the effects of the PowerCell and Tranquility Base tend to be additive.

Blind Testing
I was very curious if non-audiophiles could consistently hear when the FEQ was turned on. I enlisted the help of my wife and a neighbor, both non-audiophiles with no expectations of how things should sound. Since the power light on the FEQ is in the back of the unit, they never knew when it was on. In fact, I never told them when I turned the FEQ on and off. I just wanted to see their reactions. Also, my test subjects did not listen together and help each other. In each case, my wife and neighbor had no trouble hearing when the FEQ was turned on. Both stated the sound was bigger and clearer. My wife would shout out “bigger” and then “smaller” as I powered the FEQ on and off.

More Than Just A Tweak
Over the years I have tried and owned countless products that have claimed to improve the sound of an audio system. But I have never heard anything that was as effective in elevating the performance of a high end system as the combination of the Synergistic Research High Frequency Transducer and the Frequency Equalizer. Soundstage, noise floor, bass detail and dynamic power, midrange and high end clarity all improve with the use of these products. I feel that both the High Frequency Transducers and the Frequency Equalizer should be used in combination as together they offer far more in performance than when either is used alone.

I know that some of you will be wondering where is the technical explanation of how the HFT and FEQ achieve these startling sonic results. I don’t have that information nor was it provided to me. I do know that the HFT and FEQ do what Synergistic Research claims that they will do in my system. So there is no baseless marketing hype here. As far as I'm concerned, these products live up to Synergistic Research’s claims and advertising.

The Synergistic Research High Frequency Transducer and Frequency Equalizer will become a permanent part of my audio system. Removing these components is simply unthinkable given the quality of the sonic enhancement achieved with their use.

So Steve, er Mercman, where do you place the Feq, anywhere? When you plug it in does it vibrate? Does  it work without the Hft's? 

Steven Plaskin's picture

Yes theob, the placement of the FEQ is not critical. The picture you see is an area next to my fireplace at the rear wall of the family room. I placed the FEQ where I had some room. I have so many different USB cables, drives, etc. But this area is great for me since I can spread all of these things out. And no, the FEQ doesn't vibrate.

The FEQ does have an effect without the HFTs, but the combination is the way to go. 

So says Mercman smiley

theob's picture

What is this ground plane you talk about in your review? Is it the same as the ground plane phenomena that is all over DYI Audio? I tried searching Synergistic's web site but found nothing.

Steven Plaskin's picture

How Synergistic executes the ground plane is unknown to me. But it is used in the Tranquility Base, the Transporter, and the PowerCell. I have reviewed these products and liked what I heard.

Again, some readers will find that explanation to be wanting, but that's all I have. 

Jacob Roland's picture

I was curious about the lack of a thorough explanation of what the HFT and FEQ actually do, and how they go about doing it.  I posed this question to Synergistic Research on their facebook page:

"Looking forward to a video (or something) from Synergistic Research explaining exactly how the HFT and FEQ do what they claim to do. The impressions are enticing, but no one has explained the science behind how they affect the sound."

This was their response (unedited by me): 

Jacob the FEQ works on low frequency harmonics as a signal generator producing a ULF pulse wave while HFTs are high frequency resonators that operate outside the limits of human hearing to clean up high frequency harmonics. This in turn reduces resonant harmonic distortion in frequencies that are audible to human beings . Both are sold with a 30-day no risk money back guarantee so you can discover and decide for yourself whether or not they're right for you.

Steven Plaskin's picture

I also asked similar questions. I had to make a decision:

1: Run the review since the products accomplish what Synergistic says they will do.

2: Refuse to do the review unless an explanation is supplied that I understand.

I decided to go with the review since I obviously liked the HFT and FEQ.

But this situation is not unique to Synergistic Research products. I have 2 engineer friends that have told me that a number of manufacturer sites don't make sense to them. I asked my friends to comment on sites I was interested in.

Now this won't satisfy everyone, but for me, I'm more concerned how the product sounds and if it does what the manufacturer says it will.

Jacob Roland's picture

Your review was excellent, and I found it very informative.  No one (in their right mind) is questioning you running the review.

I just posted the response so that others might have an explanation of what the products actually do.  Straight from the horses mouth, no less.

Steven Plaskin's picture

Thanks for the kind comments Jacob. And I do appreciate your post and the information you supplied to us.

What's inside the box?

Ted Denney Lead Designer Synergistic Research Inc.'s picture

Jacob,
HFTs are high frequency transducers as is clearly stated in the name of the product, while the FEQ acts as a low frequency RF dither in a listening room or space. That this explanation may not suit some is not my concern. Seventeen years ago I developed what would become the world's first commercially successful AC Power Cord that went on to sell over 10,000 units during the AC Master Coupler's 14 year production run. That power cords play a major role in the performance of high end systems is now obvious to most audiophiles. And despite a mountain of empirical evidence suggesting power cords effect the subjective performance of audio systems, they remain a stumbling block for some. No level of explanation can persuade people who refuse to listen to their systems.

As a designer of audio products I do my best to concisely explain what my products do and how they sound when used in an audio system. I then leave it to the end user to decide for themselves whether or not my products are right for them. To this end all Synergistic Research products are available for inhome audition with a money back gaurantee if not satisifyed.

Ted Denney Lead Designer, Synergistic Research Inc.

Jacob Roland's picture

Ted,

I shared your explanation here because I felt it was a good description.  Until you provided it, no website I found had that information.

I did realize that HFT stood for High Frequency Transducer, but wanted a layman-level explanation for how it improves room acoustics.  You provided that answer very clearly.

I have heard nothing but positive feedback from people who actually use your products in their own systems, and actually listen to what they bring to the table.

Kudos for being an audio innovator.  Keep up the good work!

Bill B's picture

 If X (this product or any other) makes EVERY aspect of sound better, and has NO negative effect on any aspect of sound, then there is something fishy.  Because nothing like that exists.  E.g., read a stereophile review of a massively engineered & designed $55k power amplifier (like I did yesterday), and there are pros and cons.  The high end amplifier is super great but it still has its strengths and weaknesses.  As does everything else I've run across in this universe.

Steven Plaskin's picture

Nothing fishy here. Remember, this was the result with my system, my room, and my sonic preferences. 

I did not find any negative aspects to the HFT and FEQ, UNLESS you like a warmer, fuller bass with less midrange and high end defintion. Perhaps some people prefer a smaller soundstage.  I imagine that on some systems, the HFT and FEQ will not be preferred. 

One has to try this stuff.

Bill B's picture

I'm glad you found that result with your system.  I have a rule that something has to be fairly plausible to start with, before I go for it.  That way, I don't buy "too-good-to-be-true" claims that are offered to me, even if they have a free trial period - one has to filter out the chaff.   

In the designer/manufacturer's excerpts above, there are only 3 sentences in answer to how the stuff works, and those sentences sound vague and fuzzy at best.  The larger amount of what he says is defensive and self-justifying and it sets off bs detectors in my head.  Maybe the items are great. But for items that I KNOW work well, such as speakers or components, there also happens to be extremely solid reasons why they work.  

The designer gives apparently self-contradictory explanations of the HFT's anyway - he first says they are resonators.  Then he says they are transducers.  Uh oh.

A transducer can't resonate?

Bill B's picture

Sure it can, and my front door can resonate too, but I don't call it a transducer.

Jacob Roland's picture

It seems like you're splitting hairs here, as you know what Mr. Denney meant.  

It is clear that the HFTs and FEQ are affecting the sound in a real way, it's not just smoke and mirrors.  Now, your mileage may vary depending on your system, listening room, and sonic preferences; but based on third party reactions, the HFTs and FEQ do what Synergistic Research claim they do.

Bill B's picture

Hardly "splitting hairs" to point out a large and qualitative difference between types of devices. I do not know what mr. Denny is saying and am trying to find out. I am afraid he  does not know what he means either. I'd be happy if he gave a meaningful explanation. If he can, then he can have me as a new customer. Because I would love to have  passive peanut sized devices that can improve every aspect of sound. 

Ted Denney Lead Designer Synergistic Research Inc.'s picture

Bill,

HFTs are transducers that also act as resonators. How they perform as both transducer and resonator are directly related to how HFTs are manufactured which is a trade secret, at least until the patents are granted. For anyone wanting to try HFTs and FEQs in their system we offer a no risk 30-day trial period; more than enough time to determine wheather or not these new devices deliver the benefits we claim.

Yours in music,
Ted Denney III Lead Designer, Synergistic Research Inc.

Recorder's picture

Thank you for the review.  I appreciate your including the blind test.  

Given that the FEQ requires two electical outlets, I am concerned about how it would fit into my system, which has limited plugs on the power conditioner.  Did you test to see whether either plug benefits from power conditioning and, if so, do they generate their own noise on the power line, as do digital components?  If they benefit from conditioning but do not generate noise on the power line, they should be able to share a conditioned line with analog components.  

Ted Denney Lead Designer Synergistic Research Inc.'s picture

Recorder,

Regarding two seperate plugs on the FEQ, one is for power and the other for an internal Ground-Plane. We have found the FEQ preforms best when its powersupply is plugged directly into a Synergistic Research PowerCell. This is in large part due to design similarities / compatibality between the FEQ and the internal EM cell found in SR  PowerCells. We cannot however confirm wheater or not this holds true with other types of AC filtration. You will need to simply try an FEQ plugged directly into the wall and again into your power conditioner and pick the option that sounds best to you. Regardless, the FEQ performs no matter if you plug it into a PowerCell, or directly into the wall. The second plug for the Ground-Plane will most likely perform best when plugged directly into the wall. Lastly the FEQ does not create or emit noise on the AC or ground so it can be used with analog components without fear of contamination.

Yours in music,

Ted Denney III Lead Designer, Synergistic Research Inc.

Recorder's picture

Thank you.  That was very helpful.

Bill

Steven Plaskin's picture

I was under the impression that the power supply is not a switching power supply. I'll double check that with Ted.

The FEQ does benefit from power condtioning. at least with the PowerCell I tested.

You should have no problem plugging everything in to your power conditioner with the analog components. But again, I'll send Ted an e-mail about this.

tnargs's picture

Don't worry, even if it is a switching power supply, all you have to do is put it on the Tranquility Base by the same company for 'under $1000' and it will be 'transformed into near state of the art' power supply.wink Just have a look at the claims for the Tranquility Base on the website, Steven, and you will start to realise what you are dealing with here.

I presume, when confronted by super science that only one person in the world has a grasp of, apparently, you will of course Steven conduct some decent measurements in your room before and after, so you have an idea of what if anything is going on with the sound waves. Yes? If you accidentally forgot, perhaps it is not too late to do them now and publish?

After all, your first obligation is to your readers, yes? Surely you don't put suppliers and salesmen first (which would make you untrustworthy to readers)?

Michael Lavorgna's picture

Yes?

Perhaps you're new around here but we don't measure. We listen and report, not exactly a new concept. Seeing as our readers also listen, we feel this serves their interests really well.

Recorder's picture

Thank you.  That was very helpful.

Keremz's picture

I own a Powercell II, Tarnquility base and Acoustic Arts resonators plus all my cables are SR products. I can not imagine listening to my system without the T Base. AA and the Powercell. So I guess theres no need for me to point out that I am looking forward to trying these new goodies from SR in my system. But I wonder if they will work with the AA 's or it will be a either or kinda situation? 

Steven Plaskin's picture

It will work with the AA as they solve a different issue.I was told this by Peter Hansen of Synergistic Research.

You are in for a real treat Keremz.

kensargent's picture

Hey, if these things are this good, why stop at just five of them?  Why not cover the whole wall with them?  Gosh, why not a room full of them?  Maybe even a bazillion or so?

Boys, the idea is that EVERY really good component you own (or wish you did) is designed with some specificity.  Even the components inside that component are specified for a reason.  For example, if you really like the way a particular midrange driver sounds, imagine what would happen if you increased its' compliance.  What would that do to the sound?  Or what if you decreased its' compliance?  Which is better?  You would probably find that its' compliance, like most of its' other design attributes, is optimal at some particular point.  Go above that, and performance suffers.  Go below it, and performance suffers.

The point is simply that "more is better" ain't necessarily better.  And any device, like these magic anti-cones, must follow the same rationale.  If they really do make things better, there are a certain number of them (for a given system) that will be optimal.  Go beyond that number and they probably will "over-do" something or other.  And if they were actually designed to do something, their designer would probably know what that optimum level of "something-ness" is.

So please, follow this product closely, and once the patents are granted, tell us what the optimum amount of "something" is that our systems really need.  And while you're at it, take a look at that patent application and see what it says.  My guess is that vagueness is not rewarded by the U.S. patent office.

Stay tuned.

Ken,

HFT and FEQ are patent pending and as such, thier details are a trade secret until the patents are granted. As for how many HFTs to use before reaching a point of diminishing returns please see the following link which should answer many of your questions.

Synergistic Research has posted instructions for placement of the HFT and FEQ at their home site.

Erasmus's picture

As Mr. Denney is following this thread and a patent is pending both for the HFT (which seems a remarkable concept) and the FEQ, could he kindly inform us as to the application numbers for the said patents? A search through U.S. Patent and Trademark Office's patent application database did not produce any relevant results with either Synergistic Research as assignee or "high frequency transducer" as keyword. 

Steven Plaskin's picture

I added an HFT to each side of a Benchmark DAC-2 HGC DAC and a Wavelength Crimson / Denominator DAC. In both cases the addition of the HFTs to the DACs resulted in a larger soundstage. I was simply amazed at this!

judmarc's picture

Folks familiar with my previous posts here and on other forums will recall that I'm someone who feels that bit-perfect players, digital cables, etc., can all differ in sound, and I personally believe I've heard them do so.  Same for power cables, which Mr. Denney mentioned.  But in evaluating Mr. Denney's claims - not from an engineering standpoint, which I'm not qualified to do, but from the standpoint of the trustworthiness of previous claims, specifically regarding cables, since he mentioned them - I offer the following from Synergistic's web site:

By applying a two million volt signal to a cable at a specific pulse modulation, and ultra high frequency for an exact duration of time, we transform the entire cable at a molecular level through a phenomenon called Quantum Tunneling.

This quote can be found at http://www.synergisticresearch.com/tesla-series/tesla-series-technologies/ .

Now quantum tunneling is a phenomenon of quantum mechanics, a series of laws that describe aspects of how the universe works.  Let me repeat those last four words: how the universe works.  Quantum tunneling occurs all the time, everywhere, no two million volt signals required.  The statement on Synergistic's web site is roughly the equivalent of saying, By applying a two million volt signal to a cable at a specific pulse modulation, and ultra high frequency for an exact duration of time, we transform the entire cable at a molecular level through a phenomenon called Gravity.

This leads me to be quite skeptical of other claims from Synergistic with regard to how their products are supposed to work.  Whether they alter the sound of a system is another matter.  But for me, after reading the "quantum tunneling" description on their web site, Synergistic is working uphill in terms of convincing me their products work along the lines they claim.

Bill B's picture

The company's "explanations" are fuzzy at best, and literally unbelieveable at worst.  Of course "Quantum Tunneling" is pure bs in they way they slap a cool sounding name on whatever break-in procedure they claim to use on their wires.

I think the reviewer's responsibility for products like this is heightened.  Readers are much more understanding of a reviewer's subjective evaluation when there is a realistic basis for it.  It can be helpful for a reviewer to say he heard a clear midrange from a speaker, and say it might relate to real factors, such as cone material/construction, first order crossover design, narrow baffle, whatever.   But when a product essentially declares that it works by magic, then it is important for readers to look skeptically at the reviewer's merely subjective evaluation.  And especially so when the reviewer does not have any understanding of how the product would work (or any real curiosity about how it works).  To say that passive bits of aluminum (HFT's) work in every circumstance, only for the better in every case, and that they work if you stick the product on any of the walls, or on speaker cabinets, or on a cable - nuh uh.  "Extraordinary claims require extraordinary evidence".

 

Ultrarunner's picture

Well, I don't know anything about Quantum Tunneling, and I find some of the Synergistic website's explanations a little "out there".  But...

I sat through the Bose demo at RMAF a couple of weeks ago two times.  I don't think anyone who was there could deny the dramatic improvement made by the two new Synergistic products.  I bought 10 HFT's but was still wondering if I did the right thing. They sat on a shelf until I saw this review and spoke with a helpful Scott Walker about placement suggestions, then started to experiment.

Wow, these things are amazing!  I was predisposed to not like them because I'm a minimalist and like to keep the system free of extra wires and devices.  But there is no way these are going back.  Just changing the placement of one of them can have a major effect.  Even a blind AB comparison is a piece of cake. Just ask my wife who has no idea what HFT's are, but just appreciates that the system has been raised to a whole new level.

Thanks for the review Steven.  Thanks Ted!

judmarc,

When naming Synergistic Research products we attempt to be as clear and concise as possible so that a products name has a direct correlation to its function or construction.

Examples:

Element Series cables: Element Copper- cables with copper conductors in an air dielectric, Element Tungsten- cables with tungsten conductors in an air dielectric , Element Copper Tungsten Silver- cables with copper, tungsten and silver conductors in  air dielectrics, and so on.

Active Shielding: Voltage and current applied to the shield of a cable outside the signal path.

HFT or High Frequency Transducer: A small transducer operating at high frequencies reacting to and converting one form of energy into another form of energy.

FEQ or Frequency Equalizer: A low frequency pulse generator that acts as an RF dither for RF and EM noise in a listening room or space.

As for Quantum Tunneling we could not be more clear or forthright regarding what this process entails. Simply stated we apply a 2 million volt signal generated by a large purpose built Tesla Coil outputting a precisely tuned and calibrated pulse modulated signal that passes through air until it strikes a targeted conductor resulting in a transformation of how the conductor reacts to signal thereafter. We even show pictures on our website of a PowerCell being zapped by one of the large Tesla Coils in our factory. That some people take issue with a sales mark, Quantum Tunneling, is unfortunate given the fact we explain exactly what we are doing, and why.

The bottom line.  All Synergistic Research products are made available to qualified buyers through a no-risk in-home audition. People who purchase Synergistic Research products do so with a full understanding of what they are purchasing after first experiencing our products in their home systems risk free. For the most part it seems people who take issue with Synergistic Research have never tried Synergistic Research, instead prefering to argue endlessly on anonymous internet forums.

Yours in music,

What kind of energy do the HFT's convert sound waves to?

Over many decades of home audio I've come the conclusion that what we measure is just the tip of the iceberg.  Often specs are a somewhat false indicator of musical truth.  Our ear/brain seems to know when it's hearing real music, and when it's not.  And unlike our visual sense, where we can live quite acceptably with what's essentially a digital source (frames per second) due to persistence of vision, our sonic, human equipment detects digital versus analogue pretty easily.  

Ted and company have ventured into realms that we often find hard to correlate with our sound system experiences.  When it comes to issues that seem to live outside of our understanding or seemingly our "hearing", electrical power and sub and hyper sonic frequencies, aren't often thought to affect our perception of sound.  Clearly that's not the case, and the technology that Ted's come up with demonstrates this.  

I've been using SR active interconnects for quite awhile, along with PowerCell technology.  It's made a significant difference in my audio system, though I didn't expect it would.  Recently I installed a couple 5-pack HFT's along with the FEQ.  This made as big a difference in the quality of sound in my room as putting in a couple of Wilson Alexia's or the gear that powers them.  That may be less true in other rooms that are more hospitable to electronics, but I didn't fully know what I'd been "missing" until I installed this room "treatment".  

All I know is that the music emerges without the room constraints that have colored or worse, hidden the inner details, overtones, and textures I'd been missing.  Clearly this has been the most cost effective addition to my music environment ever.  Certainly beats building a new sound room!
