Cerious Technologies NEW Graphene Cables
Now, this is not a advertisement, just a posting sharing my experience on some well made great sounding cables at a very reasonable price. Besides, I don't think Cerious Technologies is set up for a big influx of cable orders.
But, if you get the chance to try these cables, please do.
I have been interested in the newer cables coming out that are using Graphene as a conductor. SR cables seemed interesting, but I always hated the way there cables had all those extra wires (with the active shields and such). I then noticed an ad early in I think November or December from Cerious Technologies for Graphene cables. I investigated how the cables were assembled and it seemed like quite a laborious process.
I ordered (with a 30 day money back guarantee) the balanced Graphene interconnects, and boy did they impress me. Such depth, soundstage, realism, frequency smoothness, effortless sound. I was truly impressed! I now have a complete loom of the Cerious Technologies Graphene cables. That is; interconnects, speaker cables, digital cables and power cords.
I ended up selling all of my other cables and to those of you who have read my postings know that cables have always been my curiosity.
So, as I began this post, let me again iterate, I have no alliance to the company, my posting is for those of you looking for an great alternate high quality Graphene made cable without spending a fortune.

First, I wish to extend my sincere sympathies to Bob and his family for their loss. Second, I wish to repeat the concluding comment of my first post in this thread, dated 2/11/2017: “… based on the experiences that have been reported in this thread I don’t doubt or question that Bob’s cables are outstanding performers, whatever the reason may be.” Third, regarding the statements about technical matters that Geoff has made in his recent posts in this thread, what he has said is correct. And perhaps it will minimize the back and forth arguments that may ensue on Monday if I elaborate further. It should first perhaps be added to what Geoff has said that the **extremely** slow “drift velocity” of electrons that occurs in a cable in response to application of an electrical signal, and that occurs **in conjunction with** the near light speed velocity at which the signal propagates, is superimposed upon random electron movement that occurs at what is known as “Fermi velocity.” That random movement of electrons occurs in a conductor regardless of whether or not a signal is present, and is vastly faster than drift velocity, but vastly slower than the speed of signal propagation. See this reference: http://hyperphysics.phy-astr.gsu.edu/hbase/electric/ohmmic.html So what does the electrical signal, that propagates at near light speed, consist of? As Geoff stated it is an electromagnetic wave. And like electromagnetic waves that propagate in free space, such as light and radio waves, it consists of photons. See the following Wikipedia writeup for a description of what a photon is: https://en.wikipedia.org/wiki/Photon Simply put, a photon is the smallest elemental unit of electromagnetic energy. It has the properties of both a particle and a wave. For example, light exhibits wave properties under conditions of refraction or interference. Particle properties are exhibited under conditions of emission or absorption of light. And although photons are most commonly thought of in the context of light, they are what comprise any kind of electromagnetic wave, including visible and invisible light, radio signals, X-rays, gamma rays, microwave radiation, and any kind of electrical signal, whether transmitted through the air or through a cable. Including audio signals. In the case of an electrical signal transmitted through a cable, however, the electromagnetic wave does not travel within the conductor. What travels within the conductor are electrons, moving **very** slowly. The electromagnetic wave travels at near light speed just outside the conductor, through the insulating material. Which is why, as I said in my post dated 2/11/2017, the near light speed velocity of the signal depends on what is known as the “dielectric constant” of the particular insulation. Finally, how does one reconcile the very slow drift velocity of electrons within a cable with the associated near light speed propagation of the signal? The way to think of it is that the application of a given voltage at one end of a cable will cause a very slow drift of electrons into or out of that end of the cable, depending on the +/- polarity of the voltage at any particular instant. A corresponding slow drift of **different** electrons will occur at the other end of the cable, as well as at all points in between. The movement of the electrons at the end of the cable that is opposite the end at which the signal is applied will be delayed from the corresponding movement of the different electrons at the end to which the signal is applied by the amount of time it takes for the signal to propagate the length of the cable, travelling at near light speed. That is my understanding of these matters, at least. Regards, -- Al

Hi a25105, I appreciate your kind comment. There are far more legitimately terrific audio products available than I could ever hear or certainly own. I'm very content with what I have but readily acknowledge that there are other options available as good (or better) than what I own. My system consistently provides an emotionally engaging listening experience and that satisfied my ambition. Charles |
Charles, Same reason that I posted here since Frank, David and yourself are the few ones that I trusted and respected here. Since you followed this thread here and was just wondering why you have not tried any of the GE cables:) I am going to order the blue power cord and the speaker cables from Bob soon. Will keep you guys posted. Allan |
I think that’s the first time I’ve seen that particular argument used on an audio forum, the Appeal to Sympathy. Also known as Sob Story or the Galileo argument. I.e., logical fallacy. Seems to have worked quite well. I’ll have to remember that. "argumentum ad misericordiam, the sob story, or the Galileo argument) is a fallacy in which someone tries to win support for an argument or idea by exploiting his or her opponent's feelings of pity or guilt. It is a specific kind of appeal to emotion." |
Maxima95 wrote, "Geoffkait, no surprise you knew you were one of the trolls Bob was referring to. An attempt at being glib regarding a funeral when Bob is involved in one is the height of insensitivity." Lighten up, max. The reason I knew he was referring to me was because I was the one who corrected him by pointing out the audio signal is not electrons, but photons. And it was actually Bob who was glib with his snippy response. Try to keep up with the discussion. |
"rgrost Anyone trying to contact me I am away at a Funeral and will return Monday. I will respond to the trolls when I get back. Perhaps you can revel in my loss until then...Photons for God’s Sake... " "geoffkait Nice comeback. One assumes you’ll need a little time to compose a real rebuttal. Lol I look forward to your full attention when you return from the funeral on what exactly’s going on with the audio signal in cable. I hate to be judgemental but I suspect that just might be your own funeral." geoffkait - No surprise that you knew you were one of the trolls Bob was referring to. An attempt at being glib regarding a funeral when Bob is involved in one is the height of insensitivity. Many of your posts give the term "meaningless prose" new meaning. |
Iprules1962, Good comments and truth. All that matters is what does the product sound like? Do your music listening experiences improve ? A manufacturer could give the most eloquent dissertation regarding the why and how of their products. Meaningless prose if the actual listening evaluation of the product is unsatisfactory. Just listen and judge. Charles |
I have been in this hobby for over 35 years. Have one main system that upgrade every two to three years, one home theater and a system in the living room make up of older gears. In my main system I went through over 8 cables over hauls, most of the time the upgrade cost more money, the best case is paying 20% more and get a satisfactory result. I rejected so many cables either they are not my taste or not providing positive impact in my system. Some are actually downgrade to me. In general, you paid a lot when moving up and you might get a small to reasonable gain in sound, if such a match is made in your system. The GE cables is the ONLY time in my cable quest that I get significant gain in tone, sound stage, and overall realism, gained by cables, AND AT THE SAME TIME COST LESS (80% less) than my previous cables. I went back and forth, swapping out the entire loom with my previous loom and also compared with my third set of cables (which is 65% cheaper than GE) and over a month I just listen. Most manufacturers have bold claims about their technologies. Nordost claimed that their cables are tuned to a LENGTH and should not be changed in length, yet you can custom order the cable in any length. They sounded great though, and I owned them and liked them but gawked at the bold claim. GE cables claims are also had to swallow in the actual scientific sense. But they sound GREAT. One of my previous loom was Cardas, and their claims of the principle of their cables needs LSD to comprehend, at least to me. But in the right system (my previous Martin Logan), it was a great match. In short, great cables are great cables, do not be distracted by mad hypothesis and science behind it, judge them by how they sound in your system. But I seriously hope cable manufacturers be caution of explaining the "science" and the "magic" behind their cables. IMHO - as always |

Hi everyone, I skipped through the first portion of this thread then got interested around page 10. I have read through every post since and of course now I am felling the need to try these Cerious cables. Since I want to move my amplifier and that means longer interconnects, it seems logical that's the place to start. Can anyone tell me the approximate diameter of the XLR interconnects and also how is there flexibility? Thanks, Gary |
Sometimes you don't realize what you have until it's gone. After only three weeks I've really fallen in love with the effortless musical sound the GE speaker cables bring to my system. I ordered some Duelund DTC 16ga speaker wire for my second system and for the hell of it tried it on my main system instead of the GE speaker cables. Let me start off by saying the Duelund wire is quite good and an amazing bargain. After a few hours of listening with the Duelund wire I was yearning for my GE's. I wish I possessed the verbage to properly describe the musical qualities of the GE cables, but the best I can do is to say they sound right.....real.....alive.....in my system. Other than investing in a dedicated listening room with proper acoustical treatments the GE cables have been the best non-component investment I've made. The SR black fuses would be next. Does that make me a graphenaholic? |

lancelock A layman speaking here. I'm not concerned with the scientific jibber jabber. I know the impact these cables have made in my system and my ears are very happy. I also like Bob. He is a classy guy. Whoa! What? Hey, keep your shirt on. I am not attacking the effectiveness of the Graphene Cables or Bob. Let's keep this civil. |
Hello Roxy, I certainly trust your impressions. I may at some point try the GE Yellow power cord from the wall outlet to my BPT balanced AC transformer/power conditioner. My entire system is plugged into it. It requires a 20 amp plug. The Ocellia Silver Reference cord is much more expensive but their IC and SC have served me so well it seems a natural fit. If the GE cord is equally good it would represent tremendous value given its cost. Charles |
HI Charles, I don't count as a useful opinion in this case, because the only other aftermarket power cord I have used is Pangea, but I now use the Cerious Nano Reference cords (2 years) which are certainly superior. I would like to have the Graphenes instead now, because I do have the Graphene digital interconnect and it is wonderful, as well as being actually affordable, |
Hello Allan, I have been quietly following this thread and there are posters here who's opinions I respect and trust. I believe that the cables discussed are as good as is written here. I'm sure that these products would be very fine in my system as they've been for others. I'm so content with my current cables' Ocellia Silver Reference IC and SC (4 years) Coincident power cables (7 years) that there's little motivation to change. If I were to make a move it would be with the power cables. The Graphene cords do interest me as do the latest Coincident Statement power cords or Ocellia's own power cords. There's no shortage of very good options. Charles |
LAK 2-14-2017 From a technical standpoint what I would find surprising would be if there **were** a high degree of consistency among reports of where in a system power cord upgrades are found to be most efficacious. There are simply too many dependencies and interactions that are involved, relating to the designs of the specific components, how they are interconnected, the technical characteristics of the particular power cords, and the voltage and noise characteristics of the incoming AC. Many of these dependencies and interactions, such as those involving electrical noise, have little if any predictability. To cite just a few examples: 1) Bandwidth differences among power cords will affect different components differently. Wider bandwidth may improve the performance of many power amplifiers and integrated amplifiers, due to increased responsiveness of the cord to abrupt changes in demand for current (Shunyata has published some interesting papers and measured data on this), but may increase the bandwidth and overall amplitude of electrical noise that may enter or leave the component via the cord. Responsiveness to abrupt changes in demand for current will be significant mainly in the case of power amplifiers and integrated amplifiers, to a degree that will vary depending on their bias class (A, AB, or D) and on how much internal energy storage is provided in their design, among other design-dependent variables, while having little if any significance in the case of line-level components. On the other hand, power amplifiers and integrated amplifiers can feed significant amounts of electrical noise back into their power cords (as can DACs, CDPs, and other digital components), and bandwidth limitations in a power cord presumably may be helpful in limiting how much of that noise may couple into other components in the system. So there are design-dependent tradeoffs that come into play. 2) The significance of differences in shielding effectiveness among different power cords will depend on the amplitude and frequency spectrum of RFI that may be fed back from a particular component into its power cord, on the paths that may be available for that RFI to couple into other parts of the system, on the RFI sensitivity of other parts of the system, and on RFI that may be picked up from other parts of the system. All of this has essentially no predictability. 3) Voltage loss due to resistance in the cord will vary depending on how much current is drawn by the component, and a given amount of voltage loss will certainly have differing effects depending on the function and the design of the specific component. And of course differences in the AC line voltage at different locations will further lessen the predictability of all of this. In past threads, btw, Ralph (Atmasphere) has described having measured remarkably large reductions in the power capability of certain amplifiers resulting from relatively small voltage drops across some power cords. While line-level components having well regulated internal power supplies, and that draw minimal amounts of current, will likely have no sensitivity to this. And of course all of this is in addition to the variables of listener preference, the intrinsic sonic characteristics of the components in the system, room acoustics, preferred listening volumes (which can affect the frequency response characteristics of our hearing mechanisms), the kinds of recordings that are listened to, etc. Regards, -- Al
