Cerious Technologies NEW Graphene Cables

While I don't care how GE cables obtain their great sound, I find the scientific information quite interesting. I particularly applaud Al's non-condescending and non-combative approach to explaining the technical aspects of audio. All this talk of electrons and photons is above my head but I'm starting to get the grasp of it. I should have paid more attention in my physics classes! So while I may never fully understand the science behind my audio equipment, I will continue to enjoy the fruits of their scientific achievement.......beautiful music. 

Mac, 
Alet is universally recognized as an asset to this site for his technical knowledge.  Just as noteworthy for me is his unfailing decorum,  class and maturity. Mac I also have much appreciation for science and engineering.  Knowledge is a good thing no doubt.  I just don't need to know the why and how of something to enjoy it. Give me an opportunity to listen to a audio product and I'll render a verdict. 

Lack of an adequate explanation as to how something works won't detract from its performance.

Darn auto spell,  of course I meant Al not Alet. 
Charles 

Thanks for the nice words, gentlemen.

Charles, yes, I assumed that "Alet" was either an auto-correct thing or a typo.  Although that happens to be the name of a river in France.  For the record, in my case Al is short for Alfred.

Regarding your comment that followed my previous post, as previously indicated the choice of insulation material will affect the propagation velocity of the cable.  In itself propagation velocity figures to be insignificant in the case of analog signal transmission, since the propagation velocity of pretty much any cable will exceed 50% of the speed of light, and hence the resulting delay will be completely insignificant.  It may very well be significant, though, in many cases involving digital signal transmission, although in ways that are component dependent and don't have a great deal of predictability.  The propagation velocity of a digital cable factors into the rationale underlying the 1.5 meter length recommendation you've probably seen cited as usually having the greatest likelihood of being optimal in S/PDIF applications.  That likelihood, though, will also be highly dependent on certain characteristics of the signal provided by the component which drives the cable, especially what are referred to as signal risetimes and falltimes, which in turn are usually unspecified.  

FWIW, my intuitive guess is that in the case of analog signal transmission the most significant consequence of the choice of insulation material is likely to relate to the effects on the signal of dielectric absorption.

Regarding your comments about overall cable design and construction, yes, that will of course affect resistance, inductance, capacitance, "characteristic impedance," skin effect, and just about any other cable parameter one might name.  Each of which will have varying significances depending on the specific application.

One further point which may be of interest regarding the various forms of electromagnetic waves that I mentioned, namely visible and invisible light, radio signals, X-rays, gamma rays, microwave radiation, and any kind of electrical signal.  What distinguishes these things from each other, most fundamentally, is simply their frequency.  And correspondingly their wavelength.  For any electromagnetic wave, and also for acoustic waves for that matter, frequency x wavelength in a particular medium equals propagation velocity in that medium.
