The actual making of Graphene and even the cost is not really an issue. Anyone can do it. It’s the app-li-ca-tion that’s the difficult part to come up with. Kinda like quantum dots, if I may be so bold. |
lancelock, The NEO is again one of those cable makers that think outside the box. But, I ended up selling most of them. I prefer to have a complete set of the same cables. Even my highly regarded HiDiamond cables couldn't compete. |
Ozzy,
how does the Cerious power cords stack up against the Mad Scientist PC? I remember your review of the NEO was quite enthusiastic.

mapman, thanks for your posting. I wonder how the SR cables are made? They claim to use graphene in there design, albeit at much higher prices. geoffkait, You may be right, I just don't know, sorry. I do have to give Bob Grost from Cerious Technologies credit for thinking outside the box in his approach to making cables. I will also add that I had the Bybee Signal Enhancers sitting on top of my previous speaker cables. But, with these new Graphene Extremes the Bybee's sort of took away some of the sound quality, so I removed them. There must be some interaction between the Bybee's design and the Graphene Extremes. Very interesting... |
I have not seen any advertisement of anyone using graphene in audio products for its noise shielding capabilities. Conductivity in general seems to be the attraction.
Also no mention so far I can find of its use in wires for audio or any other purpose other than vendor marketing literature.
Main projected use in electronics appears to be use in semi-conductors and other apps where its apparent power delivery limitations are not a factor.
Still it is an interesting proposition to use more highly conductive materials in traditional applications. Time will tell. Almost all marketing claims alone can be taken with at least one grain of salt.
This is an interesting product as described nonetheless. Would love to be able to give a test run if not too expensive. I can see where its mixed use with other more traditional materials capable of delivering power and current needed might reap some benefit but not sure . Use of graphene in actual applications today seems to be on the rise but I wonder how cost prohibitive it might be for many apps still. High end audio is always ripe marketing ground for these things regardless.

Ozzy, if Graphene were being used as a signal conductor doesn’t it make sense that they would have used Graphene for the Backbone conductor, not copper/silver? If you Google Graphene you will see it’s primary use is in shielding RFI/EMI. And the reason is because of it’s extremely high conductivity. Graphene cannot be used as a Backbone Conductor (I.e., for the signal) because Graphene is by definition only one atom thick. That is a problem because it won’t support the current or the voltage involved. It will, however, support RFI/EMI. Also, since the Graphene powder is embedded in the ceramic it is not continuous and thus cannot be used to carry signal. In addition, ceramic is an insulator not a conductor. Thus, if they were trying to carry signal on the Secondary conductor they would be kind of shooting themselves in the foot.
cheers,

roxy54, The speaker cables are great! And I needed a 4 meter double run for my Bi-wired Eggleston Andra ll's speakers. And I must add that the power cords also are very good. He sells different power cords for different applications. Such as for Digital, Amps etc. Heck, even the Digital AES/XLR cable is much better than my previous cable. Once I completed the loom and put some time on the cables everything locked into place. geoffkait, I'm not going to continue the debate on the purpose of the graphene, assume what you may, my message however is in the sound quality. |
I bought a Nano Reference power cord on sale from Robert and really liked it. I then decided to try the Graphene Extreme digital cable. I used to switch off all the time between my Darwin Digital cable and my LAT International. That ended the day I started using the Graphene. If it gets better than this, I'd love to hear it.
I am completely satisfied, Robert is a great guy, and I want the speaker cables now. |
Right, the secondary conductor is the RFI shield. RFI shields are characterized by high conductivity. Like Graphene. |
The poured (Graphene saturated Liquid Ceramic) conductor is referred to as the "secondary conductor" explained in the link as Ozzy says.
|
|
The wire is called the "backbone" conductor. Take a look at the link that is provided. |
"Speaker cables: 10 gauge copper/silver conductors woven around carbon fiber, then injected with Graphene saturated Liquid Ceramic to fill every gap and void, apparently quite doable when the product is one atom thick.....whew!"
I hate to judge too quickly but it appears the 10 gauge copper/silver conductors are the conductor and the Graphene saturated liquid ceramic is the RFI/EMI shield. If Graphene were the conductor then one would expect the Graphene saturated Liquid Ceramic to be used in place of the copper silver, no? Try ceramic material might act as a vibration damper. Quite clever. |
Cool product. Would love to try. |
Graphene cables are being well received so far as being several steps up in performance...and for not much cash. I've so far seen from other makers (but, have not yet tried) solid designs and even one that uses powdered Graphene and now liquid-delivered...interesting, particularly the IC's, for me. Thanks for the heads up! |
ozzy i was the one who posted that on What's Best thanks for linking it, I have no affiliation with Cerious either just a satisfied customer. Bob Grost sent me that pdf after I ordered his speaker cables in case I was curious about how they are made. I originally started out with the prior Nano-Reference cables, Bob closed a bunch out here as he was about to release the Graphene line and I picked up a pair of interconnects and was very impressed. I subsequently bought a bunch of his Nano Signature power cables after buying my first and finally hearing a power cable that seemed to make an appreciable difference. I've since them upgraded to the Graphene's I have pretty much a full loom except for one Nirvana digital cable I'm still using. I really think these are great sounding cables and with Bob's direct to consumer pricing, a really excellent value. Plus he's been great to deal with, he has on two separate occasions reterminated cables for me at no charge. I highly recommend anyone giving Cerious cables a try.

I think it is part of the conductive signal. |
So one assumes the Graphene functions as an RFI/EMI shield/absorber....?
|
|
I found pictures on the web as to how these cables are assembled, very involved looks quite tedious. If I can find it again I'll post the link. |

That's my question as well. At least it's strong!
|
Graphene is around one atom in thickness. So one naturally wonders how it would be used in cables. |
ozzy,
This piqued my curiosity so I found this article about graphene and thought I would share. I think everything on the web should carry a date so you can easily put it in context but as close as I can tell this is from about 2012. I have heard about graphene in the past and I too was curious about when viable products may hit the market. Thanks for the information on Cerious cables!
