Hi Larry, that is a interesting comment about the extreme graphene speaker cable's, the wow factor has got my attention, please keep me posted of any improvment's that you experience.
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.

Breaking news! Graphene tennis rackets! Can Anyone see some uh audio applications? http://www.tennis-warehouse.com/Head_Graphene_XT_Radical_MP_A/descpageRCHEAD-GXTRMA.html?gclid=CIfu3... |

The use of Graphene in tennis rackets is interesting because the Graphene is obviously used like Graphite used to be used, as structural material, stiff and strong and lightweight, like Boron, Magnesium, Carbon Fiber and Titanium. So that begs the question, how do they use Graphene in making tennis rackets since a one atom thickness, wouldn’t buy you very much? My guess is they reinforce some other material(s) with a layer Graphene, or multiple layers of Graphene, each layer one atom thick. That’s how I’d do it, anyway. |
The Exact explanation is key to the use of Graphene. We are used to the "Titanium" card but all know it is not made of Titanium. The "Graphene X" technology used in the tennis racket is just a label for their core material, which has no correlation to the material called Graphene. Graphene has no structural elements which is why you cannot make a solid conductor out of it. Composite structures are weakest at their boundaries and seams, and any material one atom small is ALL seams. Tennis rackets are made of a skeleton of Syntactic foam skinned in various materials, usually fiberglass with a small amount of carbon fiber. While Graphene could fill in the voids in the foam it would be MUCH heavier than the air it disposes and would give you tennis elbow from the loss of damping. Heads last line was the "Liquid Metal" series which employed no actual Liquid Metal or Amorphous materials. It was a marketing slogan. This is why at Cerious I go out of my way to explain EXACTLY how we use it and why. If a company is vague - it is for a reason... |
Someone at their Peoria headquarters ought to at least proof read their (Cerious) web pages as there is a spelling error, in the product name no less! http://www.cerioustechnologies.com/cables/lcSpeaker.html "... inside the Grahene Speaker cables ...." at better than $1400 for 8 feet, I demand perfection. :) |
Rgrost, not sure why you think tennis rackets are not sometimes constructed using titanium or Graphene or other exotic materials. The "titanium card"? Tennis racket manufacturers have for many years been experimental in terms of strength of materials, you know, ever since wood rackets, which themselves are often quite interesting in terms of construction. Apparently, unless the manufacturer is lying, Graphene is used in the construction of the racket handle. Now, whether a racket constructed using Graphene is measurably better in some respect say, stiffness, than some other material is another question. I have many rackets myself, from titanium to graphite, to magnesium to carbon fiber, ceramics or composites or alloys thereof. I even have some outstanding examples of wood rackets. The titanium racket certainly appears to contain a good deal of titanium and the same with the magnesium racket. They are probably at a minimum alloys of the metals. Not sure why you think rackets all employ foam and fiberglass. That just doesn’t make sense. Just as stereo cartridge manufacturers have experimented with various materials for the cartridge stylus, you know, boron, ruby, diamond, etc, tennis racket manufacturers certainly have the wherewithal and expertise to do the same. And just from the feel and the "action" of these exotic rackets I’m sure they actually do. The ceramic racket feels like ceramic, the titanium one like titanium, etc. |
Here is an excerpt from Boston Globe: "...Novak Djokovic, who says the racquet will "give [his] game even more speed and control." Though whether or not that’s directly due to the graphene is anyone’s guess. ..." More speed and control sounds perfect for driving my speakers! Rob is right, he explains how it is being used. Most manufacturers remain vague. Again an excerpt from the Globe (different article): "..The race is on to see which companies, in which industries, focus more on marketing the word GRAPHENE, and which focus more on using the material to make substantially better products. .." |
Addendum: http://www.nnin.org/sites/default/files/files/NNIN1014.pdf cheers PS from Graphene Tracker online, HEAD’s new series of graphene-reinforced rackets are being promoted by the likes of Novak Djokovic and Maria Sharapova, with users reporting increased precision and ease of use, accompanied by decreased racket weight. In one of the early promotional videos, Novak’s new racket is called his “secret weapon”. The composition of the racket and the role of graphene was indeed secret, until the publishing of the graphene racket patent application. HEAD chose to try and protect not only the use of graphene in rackets, but also in all other sporting goods, including skis, snowboards, golf clubs, and footwear. If the patent is approved with all its claims, it is sure to rake in large profits for HEAD, as other sporting goods manufacturers will certainly follow up with their own explorations of graphene. Strangely though, the patent application does not put a claim on balls made of graphene. US patent application number 20130090193 describes the use of graphene as a reinforcing element in the build of a tennis racket. The graphene is embedded into an epoxy matrix, which makes at least a part of the racket’s structure. The use of graphene increases the racket’s performance, making it lighter in weight yet more durable than rackets used to date. The graphene also makes the racket’s stiffness along different directions more proportional, addressing a problem commonly experienced with non-graphene reinforced fibers. This means that tennis players will now have more freedom to throw their racket against the ground upon losing a point, knowing that graphene is there to help the racket survive and be used again. |
Sorry to steer this away from audio. I "Know" about this area because I have worked as a consultant to both the golf (shafts) and tennis industries designing materials for them. Adding Graphene to the Epoxy mix versus ceramic micro-spheres will add little to the characteristics of rackets or golf shafts (BTW I was a regional champion tennis player and am still a solid 4.5 player nearing 60). This is marketing pure and simple. Since we came out with products that contain Graphene, I wish you could see all the Institutes, Trade Associations, and University Grant proposals we get looking for money. Graphene will be a $20 Billion dollar "industry" this year. Again I am sorry to have added to the steering of subject away from audio (which I LOVE) to technical aspects of materials which is work for me and just plain tedious! If you wish more information on materials write me at my website and I will be glad to elaborate without taking up space on the audio forum... |
I play tennis evey day and have now about thirty rackets, ranging from Slazenger and Dunlop Muliply wood jobs, the Dunlop Max 200G, various vintage and newer Wilson, Head, Prince, graphite, carbon fiber, tungsten, magnesium, and others. I even have a Megaton Pro super widebody and Rex Professional super widebidy from Germany. To claim that the material in rackets is pure marketing is a little bit silly IMHO since each type of racket obviously has it’s own action, physical characteristics and feel, which are attributable to several factors including materials as well as geometry, strings, tension of strings, etc. Besides, why would a company like Head take out a patent on the Graphene racket technology? Doesn’t make sense. Is that itself a marketing ploy, taking out a patent? Furthermore, and more to the point, why would Djokovich comment, regarding his Head Graphene tennis racket, "It’s my secret weapon." I suppose now I’ll have to check out the French Open today at 12 and see how Djokovich is doing with that heavily marketed Head Graphene racket. ;-) Doncha agree tennis is a lot like audio - it’s a question of tweaking, materials, what strings to use, tension, vibration dampers, materials. ;-) especially what I do a lot of professionally, vibration isolation and resonance control, in terms of physics of materials. I return you to your regularly scheduled programming. geoff kait machina dynamica |
Djokovich will be out on the court in the French Open in about 10 minutes at 1:15 EDT as Tsonga retired in match preceding him. One imagines he'll be playing with the Head Graphene racket. I suspect the powers that be at Head are on pins and needles. Let's see what that Graphene is all about. Heh heh |
@charles1dad,
Quote: In my system I use a BPT 3.5 Signature plus unit that is a 75 pound 2400va balanced transformer with 10 AC outlets. 7 years of utter joy with it. I'm a strong proponent of balanced AC power for an audio system. I have a BPT 3.5 Signature that I'm happy with. Note it came with it's own proprietary L-10 power cord. Would you leave this cord alone or try the CT GE power conditioner power cord? I will be purchasing CT GE low and high current power cords from my preamp, oppo 105D, Parasound P7 and Llano amplifiers to the BPT 3.5 Signature. Thanks. |
Labo53 and Charles1dad; I have one CT GE power conditioner (blue) power cord on my Plinius SA Reference amp and one CT GE high current power cord in my other system on my Allnic T-1500 (300B) Integrated amp. I burned these power cords in for over 200 hours on my Audiodharma cable cooker and they are in my two systems (untouched or moved) now for four weeks. I believe they are fully burned in, I like them, and I'm going to keep them. Unfortunately, I've never heard or used the power cord that the two of you are referring to. At the given price, could not hurt to try them ;-)... |
infection...i have Chalice Audio 'Grail' SET mono blocks..you can do a 'Google search and read the review on Positive Feedback....the music is more coherent...vocals are more intelligible. They are musically and tonally as good or better than the CT-1 s they replaced.They give the proper weight to the music also.So far very - very good. |

jmcgrogan2...yes..i am talking about the 2 'high current' blue CT GE pcs.As for the CPT 300..i did purchase one which should arrive early next week.i will be comparing it against the CT GE red ...for a longer period of time..on my Lumin player. charles1dad...there are only 2 pair of the 'Grail' amps currently..unfortunate story as to why there are not many more. i will not elaborate...however. Chalice could have been one of the top companies in all of audiodom..if that's a word.. |
infection...'near'....the amps that were reviewed by Positive Feedback were actually the prototypes..not the final product which, in my case,and the other pair, have been upgraded many times. They are far superior to the original prototypes that were reviewed....as for the JPS 'Aluminata' pcs..i had those in my system at the time of the review. they are / were very good pcs but not to the level of the CT GEs or CPT.. |
charles...you are more than welcome to come to virginia anytime you want..would love to have you hear them. infection....you may ask..The current price is much more than the price in the review.... if you wanted a pair made...which takes about 6-8 months.....! The CT GE pcs are great..I think you would really like them.. |
I am REALLY impressed with the improvement the addition of the 2 'high current' blue CT GE pcs has made in my system. They continue to improve. Have only had the in for 50+ hours so far.Have ordered a pair of speaker cables also. The CPT 300 should be here tomorrow to compare on my Lumin..Fun Times... |
I am getting very close to actually ordering some of Bob's power cables. I would need one for a Wells amp, one for a Bricasti dac, tubed preamp, and the power conditioner. I see you guys mention reds and blues and such, are there multiple styles available for the duty cycle then? I'm trusting you guys that these are good cables based on your responses here!!! :) |
"..Bob states the 'red' cables are primarily for digital gear or lower powered devices and the 'blue' high current' pcs for most amps..you can certainly email him and ask which he would suggest for a particular piece and he would make suggestions..
Absolutely. A "yellow" PC for a power conditioner and a "red" one for a digital piece are forthcoming (along with some other stuff). |
Calloway, I look forward to your thoughts on the CPT 300. I've been burning in my CPT 300 on my cable cooker since 5/23. I'm waiting to receive Bob's GE Digital cable and Interconnects (RCA) sometime this week and then at that point I'll put them on the cable cooker and put the CPT 300 into the system for a listen ;-). |
calloway, I think you will really like the speaker cables. I am using a 4 meter dual runs (bi-wiring). lak, Congrats on the digital cables. I have both the RCA and the XLR versions. As I stated on the other thread I am using the CPT 300 on my low power equipment utilizing a DIY 8 way junction box. From there I have the Graphene Extremes going to the individual components. |
I received my Cerious Technology Graphene Extreme speaker cables and interconnects recently and now have about 50 hours on them. It took less than 2 weeks to make and deliver the cables. I was looking to replace my Audience AU24e speaker cables, which I really like, but I wanted to try something new. I also was seeking something besides my Coincident CST Extreme speaker cables (which were serving back up duty to the AU24e’s) and Coincident CST Extreme interconnects, both of which sounded a bit edgy to me. In addition, the aforementioned Coincident CST Extreme interconnects produce a narrow soundstage with smaller image sizes, which I wanted to improve upon. Based on my recent experience with other graphene based products, I had a hunch the CT GE’s would work for me. I was right! With that said, I thought I would leave a post here on my impressions on all of the graphene products that have been going into my audio system. (I recently posted my system here if anyone wants to see where my point of view is coming from). First off, I have been adding Synergistic Research Black fuses and power cords for the past 3 months. The fuses have created a greater sense of presence, adding a wonderful sense of three dimensionality, which is one of my system goals. Music is also more clear and intelligible, but not harsh or edgy at all. The improvement is very noticeable. I listened to my system with just the new fuses and my older cables and I swapped back and forth between the new and old fuses, to make sure the fuses themselves are what is making the difference. With the stock fuses, the sound is smeared and washed out. There’s no doubt, hearing is believing. Adding SR Black power cords to my preamp, power amps, dac, and phono stage led to a subtler change. There is a greater sense of having a black background, leading to even more clarity and inner detail. But there was not much of an additional effect to width and depth of the soundstage. I confirmed this by swapping back my old power cords, which are JPS Labs AC+ cables. When re-inserting the AC+ cables, the size of the soundstage stayed relatively the same, but the music got just a little mucked up, slightly more smeared. I concluded the SR Black graphene power cords are a worthwhile upgrade, and I bet the CT GE power cords would have a similar if not better effect. The CT GE speaker cables are a similar improvement as the SR Black power cords. Compared to my Audience AU24e cables, they subtly add to the sense of blackness and clarity and to the sense of image specificity. Soundstage size is the same. They do not have any of the edginess of my Coincident speaker cables. These are very listenable. Now, I must admit, I did not break down my system and put all my old interconnects and fuses back in to gauge the speaker cables impact on my old baseline. That said, as they break in, I look forward to even better things ahead. Now for the CT GE interconnects. As background, I once had a full loom of Virtual Dynamics Master cables, and have tried almost every cable made by Cardas and JPS (except Aluminata). I currently have the aforementioned Coincident CST Extreme, Coincident CST (non-Extreme), Audio Sensibility Statement Silver, and Ocellia Silver Reference cables (ranked worst to best in my opinion). I tried the CT GE’s with my dac to preamp, and also with my disc spinner. I find these interconnects to be free of edge and glare. Even with all the other graphene products installed – the fuses, power cables, and speaker cables – i can tell the CT GE interconnects are a benefit to my audio system. The sense of blackness and separation of instruments, of placing images in more clearly defined spaces – all are much better. A pleasant surprise for me is that the blackness and image separation/specificity is clearly better than what I hear with my Ocellia cables. On the other hand, the Ocellias are more natural and organic. They sound more full bodied and harmonically rich, but a tad more diffused. To be honest, at this point with the CT GE”s at 50 hours, I like the presentation of the Ocellias a little better. The Ocellias provide more of a non-analytical, addictive quality to music listening for me. But as much as I really like them, I put them up for sale. The Ocellias are really nice and those of you that own them are fortunate to have them; I would have completed my system with them and not opened my eyes to Cerious Technologies if Ocellia’s prices were the same as they were 5-6 years ago. As it is, I am glad I found out about Cerious Technologies. Bob has been a great guy to deal with and is someone I am comfortable doing business with, so he will be getting an order for more cables from me soon. I might regret this, giving up such a great cable as the Ocellia, but the CT GE interconnects are very promising in my opinion and will only get better as more hours are put on them. Another thing of note is that with all of these graphene products I find myself able to listen at much lower volume levels, typically 72-78db nowadays, versus the mid-80’s before all of the upgrades. Music still sounds full, impactful, and detailed at these lower listening levels. These graphene products have been wonderful for my system. Definitely worth checking out, especially since both companies offer a money back guarantee if you don’t like their products. Postscript, it’s been a few more hours with the GE cables, and together they are sounding more real, natural, and organic. Very nice. Break-in: What a concept! |
