Cerious Technologies NEW Graphene Cables

But if I remember correctly Al has mentioned that the music signal, whatever it is made up of, like electricity in general, travels the path of least resistance.

Hi George,

Thanks for thinking of me, but no, I never would have said that, in this thread (which I have not participated in until now), or in any other thread. The old saying that electricity follows the path of least resistance is a somewhat misleading oversimplification. Electric current flowing between two points will utilize all of the paths that exist between those points, and will divide up between those paths in inverse proportion to their resistance. (And that’s even a bit of an oversimplification, because at frequencies other than zero Hz, i.e., other than at DC, inductance, capacitance, and impedance enter the picture, in addition to resistance). So a greater fraction of the current will utilize a lower resistance path than the fraction of the current that will utilize a higher resistance path between the same points, but all available paths between those points will be utilized to some degree.

Also, as Geoff indicated information in an electrical signal is conveyed in the form of an electromagnetic wave, which propagates along a cable at a substantial fraction of the speed of light in a vacuum. Generally somewhere between 50% and 98% of the speed of light in a vacuum (which is about 186,000 miles per second), depending primarily on what is called the "dielectric constant" of the insulation that surrounds the conductors in the particular cable.

So for example the time required for a musical signal to propagate from one end to the other of a 10 foot cable having a propagation velocity of 75% of the speed of light in a vacuum would be approximately 0.000000014 seconds. In other words, essentially instantaneously. (Consider the fact that just one cycle of what is considered to nominally be the highest audible frequency, 20 kHz, is several thousand times longer than that, with mid-range and bass frequencies having cycle times that are far longer still). Any differences in that 0.000000014 second figure due to whatever effects strand jumping may have on the electromagnetic wave therefore figure to be completely insignificant.

That said, 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.

Thank you Al for taking the time to explain this subject so clearly. It has always been difficult for me to understand how much difference in sound a wire and dielectric can make in the near instantaneous passing of a signal.  And I do think I hear a difference in cables.  I am keeping this short to not show more of  my lack of understanding of physics but really appreciate your explanations.

Since Graphene is defined as a two dimensional material, meaning that it’s thickness is only one molecule, the slurry of Graphene infused liquid ceramic used to surround the backbone metal conductors is not really Graphene any longer, but some other graphite based material. The special properties of Graphene, I.e., high strength and high conductivity are based on the premise that the material is only one molecule thick. Thus, I conclude the Graphene infused ceramic is acting as an anti vibration jacket and/or as an RFI/EMI shield. Please note I’m not impugning the efficacy of the Graphene cables. I actually think the cables would be superior to many deigns, but for the reasons I just mentioned which, by no coincidence, are the same reasons Graphene is employed in the SR Black fuse.

Thanks to Al for pointing out the audio signal travels at near light speed. Of course that means that the signal must be comprised of photons, not electrons. Massless photons are *compelled* to travel at the speed of light in a vacuum and at somewhat lower velocities in other mediums like water or copper, the actual velocity depending on the physical characteristics of the medium.

Maybe someone could make interconnects out of slow glass? 😉

I have not posted here in a long time.  But, my recent experience with Bob's Blue PC HC warrant one.  It replaced an Audience power cord SE--a decent but admittedly lesser cord than the higher end products used for comparison here--and the difference was, as you might expect, transformational.  I'm posting for those that may not happen to own one of these better cords to compare to.

For context, my system consists of an Ayre pre and amp, Gumby DAC, Aerial speaks, Audirvana +.  The Blue connects a BPT power center to the wall that runs the electronics. 

I would characterize the Red's improvements as giving the sound a vast increase in dynamics, a tangible increase in base definition and an extension of the upper regions.  I am pulled into the music more and voices create goose bumps where there were none.  It sounded so much better I wondered how one cord of a half dozen in the system could do this!!

Break-in in my system was different than often reported here.  At first, everything sounded confused and muddled, but, at the same time, I also heard immediate improvements in dynamics.  At 8 hours confusion waned, and vanished at 20.  At 40 hours, it all sounded really good--clear and immediate and tangible--only to improve in these specific aspects at hour 60.  I began to think that the flaws I heard--such as a need for tighter bass control that had improved, too--were not due to the Blue but to the other cords/equipment. 

I try to keep price out of qualitative judgements but then, it is darned attractive and can't be ignored  Regarding Bob's service that has gotten a lot of ink here:  At 12.38 PM CDT today I emailed Bob to ask which cord should be next.  At 4.09 PM, he said Red (for the DAC).  Service response time rating?  Same day response has to be considered premier league. 
 Can't wait for Red.
