Power Cords Snake Oil ??


Having been a long time audiophile living with countless high end compnents I have to wonder about the theory and practicality of high end power cords.

I have yet to hear the difference a power cord makes. Ive owned, synergistic, Shunyata, BMI and cardas. I in no way can detect any sonic signature or change. Give me a pair of interconnects and I imeadiately notice a difference somewhere in the sonic spectrum. Not the PC though. I have accomplished 4 blind tests with my friends. 3 out of the 4 they did not know their cord was replaced. All 4 were using a stock factory supplied cord. Each of the 4 tests were done on different components. Amp, CDP, Preamp & dac.

My electrical backround tells me that provided you supply the component with its required voltage bet 110vac or 220/240vac its happy. Now, change the incoming frequency from 60hz to say 53hz and watch how quickly your soundstage collapses.! This is often the case during the summer months when home air conditioners are in use and the utility company power output is taxed to the max. A really good power conditioner should however take care of the frequency fluctuations. But 110vac is still 110vac regardless of the conductor it passes through as long as its remains 110vac when it reaches the intended circuit. Does your 8k amp or preamp know the difference of the path the voltage took to reach it ? Many an audiophile will use a dedicated 20amp circut for their equipment.That is a good idea as voltage & frequency fluctuations will occur in the home circuit to to other loads on the main breaker panel but again, A power cord simply is the means of transporting the voltage from the wall to the component. IF there is a clean 110vac @ 60hz at the wall socket, no matter what the medium is to go from the socket to the component, it will still be 110vac @60hz.

Could somebody expand on this a bit more. I just dont understand it. ??

Zaikesman:
Good one, it proves there is nothing wrong with your sense of humor.
The power cables you are disscussing are basically the same; so why should you expect a difference? There is only one power cable that is truly different and commands the technology that astounds;but you won't go there because the answer sounds to radical. You chose to cling to the same old ideas and complain about the results.

Eldartford:
You are correct the power cord does not change the 60 HZ frequency. However, the PC has its own resonance frequency and the conflict between the two creates a harmonic structure that is passed into the system producing distortion.
Kt 88:
So you think installing a "FIXED PC" to audio gear is a real clever idea?
Slappy:
"Cinnamon chicken cigar";could you expand on this subject a little more?
Sean;

“Hundreds of dollars” to reverse engineer our product? Try thousands of dollars. There are about 45 custom parts that are made by hand and constructed of real exotica. The materials took over a year to source and the few companies that make them have a minimum order would not believe.
Yes it would be fun to compare notes, but you know the problems with that.
The design concepts we are using are really “off the map”. However; since the recent advent of “String Theory” as the dominant position in physics what we are doing does not seem so “out there” any more.
Sean;
No problem, I took your interest as a compliment. What makes copying difficult, on most of the models, the internal structure is bonded together any attempt to disassemble will lead to disaster unless you have sourced the replacement materials. If you would like to see a picture of these wonders: click Browse then Cables [power] scroll to Dealer Demos and click PreThrilla and Ampthrilla, the Prothrilla and Supremium are not yet posted.
Any of you Audiogoners that not yet investigated “String Theory” check it out on the “net”; its implementation is what’s going to divide the past from the future.
Zaikesman:
I didn’t say that you did; according to E. Whitten it’s 11 dimensions.
So what does “String Theory” have to do with my audio system; is that your question? Here is a list of conventional electrical engineering precepts which are employed in almost all cable designs to the detriment of all audio systems. The following would not be supported by String Theory.
1. Building a cable without any consideration of the field that surrounds the conductor.
2. Designing a power cable as an isolated entity as if is has no bearing on the performance of the speaker,amp,etc
3. Claiming that electrical and mechanical resonances are mutually exclusive phenomena.
4. Claiming inductance, capacitance, resistance are the central issues in all cable design.
What String Theory is asserting: all revolves around resonance. This has been our position for the past decade.
Subaruguru:
You said it takes you 2 and 1/2 hours to build a power cable that should sell at $250.
That comes out to $100 per hour with no dealer to take his share and no overhead, and you’re calling other people greedy!
Now let me guess, I bet you take some wire, put some insulation around it (call that resonance control) and attach it to a couple of connectors and declare it a power cord. That may work fine for power tools but it is not going to do much in terms of accelerated audio performance. We are not amateurs. We do not make a living by hiding behind words on a computer screen. We do in-house demonstrations, directly or through our dealers. We compete against the best of the best. With the introduction of our new designs, I can tell you with absolute assurance, we are light years ahead of the competition.
There are a number of people who are more than willing to slam a product without any understanding of the technology involved, have never experienced the performance and do not even know anyone who has! Yet these individuals are eager to express violent opposition based solely on their long accumulated assumptions.
S23Chang: I believe Nikola Tesla was the first string theorist when he said,” Resonance is the tune the universe is dancing to.”
Hi Guys:
One of the many things I have discovered on my journey through audio: When you set out to push the envelope, sometimes the envelope pushes back.
Zaikesman:
Your mind has a tendency to live in the shadows; no, that is not reason it happned that way. We could not get the speaker to work properly,we traced the problem to the power cables at this point we realized a more advanced pc was going to be absolutely necessary. Like I said before this process evolved over a 4 year period.
Flex:
In my 45 years of audio I have seen an endless stream of proofs or “White Papers” that had nothing to do with the performance of the product; almost all were based on educated hype. There is an old saying in audio: “If it tests good and sounds bad it’s bad; if it tests bad and sounds good it’s good.” The truth is if we won the Nobel Prize for Physics you would then be saying: “Physics theory has nothing to do with great sound”.
S 23 Chang:
It took a long time to develop this technology. As you have stated, explaining it without giving away the farm is a challenge. Another problem, the explanation keeps moving. As we learn more about how it works the new understanding it invalidates part of the old explanation, I am sure you are familiar with this part of the learning curve.
Flex:
You are right there has been 80 years of "firmly published measurement and engineering theory";and look at the mess it has created.
Face it flex, you are a slave to the past. There are no words that will ever convince you of anything. That's not necessarily a bad thing, it just the way you view the world.
I think you sometimes forget that is a forum for the exchange of ideas, demands of scientific proof are better served in another setting.
Flex:
Is the one you are referring to?
"I think people basically *are* saying theoretical physics has nothing to do with great sound". I am not sure if he believes this or is saying that others do?
We believe it has everything to do with great sound that is why are so intrigued with "String Theory" because it is saying what we have experienced in the lab; there are no isolated events, all electrical phenomenon are interrelated.We are presently focusing on the relationship
between impedance and resonance. It does sounds strange!
"When we compare what we know to what we don't know, we can truly say we know nothing",Albert Einstein.
We consider the power supply/power cable assembly as one unit. It is the most misunderstood and most important aspect of an audio system. We take measurements but not the kind you’re talking about. Here, sign wave analysis reveals partial insight to a problem that is very unique; you must make the map fit the territory not the reverse. Resonance interaction, field theory and field isolation all play a major roll in power conveyance and interactive symmetry. In other words, the pc must convey power with no lag time and match the power supply's resonance signature or disruption in flow energy will occur. This problem requires a break from traditional thinking to achieve the goal we all are looking for. Because power supplies are not standardized an array of alternative resonant signature designs must be utilized to match every application.
Eldartford:
“...Hypothesis is tested by examination of data from tests that ought to be affected by the hypothesis. If most of data corresponds with what would be predicted by the hypothesis, it becomes a “Theory”.
The intention of the following statement is to promote the evolution of a point.
Many months ago you were constructing a power cable. We had a brief discussion about its design.
I suggested with an admitted lack of sensitivity: “That’s not the way it works”. Do you remember? Now you state: “I consider power cord effects to be a hypothesis”. When one has *NO* research to back up a design what other conclusion could you have? Before constructing your cable did you know or have an insight into the importance of:
1. Resonance signature of the conductors, both as a single “filament” and as a bundle?
2. Did you know the resonant characteristics of the dielectric used and its effect on the conductor bundle?
3. Did you know how this package would interface with the characteristics of the connectors used?
4. Did you know the field interaction between conductors or “filaments”?
5. Did you understand the field relationship between the conductors that were in polarity opposition?
6. Did you understand how this construction was going to interact with the attaching power supply?
If you did not have this knowledge, then I agree you were truly constructing a hypothesis. For a cable to be an effective tool with dramatic performance it must be a theory based on results not something founded on belief.


Zaikesman:
The God thing was a joke. I did not see anyone as a potential customer; what I would like to do is contribute to a change of direction in audio. If you ever decide to look for the “Isness” I’m sure you will never find it in “belief” of any kind; but that is another topic. Have a good one and well get back to you later.

Eldartford:
I respect the fact you built your own pc, keep it up. You and Zaikesman [and a few others] have been tough as nails but also interesting. I have enjoyed the dialog and will continue to look for you guys. I hope you both have a happy new year.

At times it does seem that change is moving very slow. This is because most people are not in search of it. Most are content with the same old thing wrapped in a new container; so this is what we get. I think there is a sense of security with the known and many find that appealing. When the Wright Brothers flew the first plane the public reaction was not one of joy but one of shock; brought on by a belief that the feat could not be done. New and creative ideas are usually met with indifference or disbelief; this has been the norm throughout history.
Kt88:
"Circuit heads" don't "get" physics. I deal with these guys all the time; you can't use architecture to design an amplifier and you can't use electrical engineering to design an audio cable. It's that simple!
rats@mong.us:
The amount of distortion generated by traditional cables is huge.
We have just completed a ported dynamic driver type speaker with no x-over. The speaker will not perform well at all without our new power cable design feeding the electronics. The problem is that acute. This speaker is the results of 4 years of hard research.
Clueless:
For a guy who admits he does not know what he is talking about, you certainly have some very strong opinions.
Zaikesman:
Anything connected to the system with the "Direct Drive" speakers in place, that does not have incredibly low distortion levels will have that imperfection announced loud and without any cause for doubt. The speakers were intended for those who already have our cables; they will not work with lesser designs.
Kt 88:
You sound like the "enlightened" individuals who think the moniker "Corona" is referring to a Mexican beer.
Matchstikman:

We have found the same degree of improvement whether we are attaching our power cables to digital or analog audio equipment. A real insight manifested when we linked a pc to a battery supplied preamp. Since the unit stores it energy in the form of DC we felt that no real performance benefit would occur with a state of the art power cord; to the owner’s and our surprise the improvement was substantial. This probable means that while the unit is drawing energy to store the effect the pc have on the electromagnetic configuration is not altered even when converted to DC and stored in the battery.
Kt 88:
The lab amp, which we built, sits on a 1 ½” thick solid walnut plinth. Its transformer is separated from the electronics; the rectifier bridge is a soft recovery design. We spent 6 months developing the emitters made from resistive copper wire rather than nichrome; the diameter and length were tuned to the amp’s performance. To our knowledge this had never been done before. We recently discovered that YBA’s top of the line $35,000 amp has the emitters removed completely from their transistor design which is even better. Tube designs don’t use emitters but they have to deal with output transformer problems. We used Hovland’s best film and foil capacitors and Vishay’s best resistors. The transformer and power supply were wired with very heavy gage solid core with an isolated symmetrical configuration; the transformer temperature is controlled by constant convection flow. We have compared this amp with CJ’s and many others; bottom line: there is no comparison. CJ will probably tell you if they built an amp like that it would cost a fortune. We have no plans to sell this amp but 6 years ago when we built it the projected price was about $6500; in today’s market it would be a bit more.
Zaikesman:
Z, I respect your input but you’ve got your needle stuck in the same old groove. Think about this: We are generating an electromagnetic null down the center of the power cable, the field effect of the two conductors in opposition are then neutralized, you now have two polarities in electromagnetic isolation. This whole movement is created by a manipulation of field resonance; this is “String Theory”. Do we have enough proof to satisfy the scientific community? No. We*DO* have the technology to create a product that works like nothing has before. We are advancing the state of the art. We are *NOT* in search of a Nobel Prize. Our business is producing cable products that yield extraordinary results but somehow this is not good enough, you are more concerned about the bottle than you are about its contents. Now if you can supply us with a better explanation I would like to hear it. Or, I think, you once said it would be better if we gave no explanation; for you that might be acceptable but for many others that just would not do.
Zaikesman:
The central issues are:
1. Is resonance the fundamental essence or energy of the universe?
2. Does the alteration of resonance create a change in energy?
After many years of testing we came to the conclusion the answer is “yes” to both questions.
Thereafter we discovered that “String Theory” encompassed the same ideas.

Audio Application:
All electromagnetic phenomenons are based on resonance; change resonance and energy is transformed.
I can’t spend much time with this answer we are preparing for demonstration at T.H.E. SHOW in Las Vegas.
Geoffait:
With all due respect your post is the horns of the problem. Resonance *IS* energy and when it is changed the manifestation becomes altered. “Resonance is the tune the universe is dancing to”. ….Nikola Tesla
Subaruguru:
We have friends that make and sell amplifiers; the time involved in construction is about the same as one of our power cables. Our top of the line model takes about a week to construct.
Steve:
Great question! We spent years on that one. There is a conflict between the 60HZ and the mechanical resonance of the conductor, this creates the problem. Rectification and filtering will not solve it. The solution is proprietary but we can discuss the problem in greater depth when I get back from Vegas.
