Sonically -Cardas the difference between the CLEAR Loudspeaker cable ,and CLEAR BEYOND

I just wish ONE of these cable makers would have the balls to explain the engineering and scientific methodology they used to design their cables!! If I’m not mistaken, Cardas is one of the few that says they utilize trial and error to find combinations of wires that actually yield a difference in sound. They still can’t explain the science!……

CARDAS has two main factors : 

(1) their proprietary best of breed copper . 
see https://www.cardas.com/cardas-copper

(2);Design, process and engineering.

- CARDAS latest patent

George Cardas continued to work on cable designs, most recently receiving US Patent US7674973B2 for what we call the Matched Propagation Conductor. This conductor matches the propagation rate of the signal in the conductor, which is essentially light speed, to that of the dielectric materials, which are generally 30% slower than the speed of light. 

This mismatch has plagued audio cables since the beginning of the telephone age, causing smeared, unintelligible audio over long distances. Telephone companies attempted to solve the issue using loading coils, developed by Mihajlo Pupin in the early 20th century. George’s solution is much more graceful - and effective - utilizing specific wire-winding pitches and carefully selected dielectric materials, eliminating the issue within the cable, and continuously throughout the cable.

Our Matched Propagation Conductors are used in all of our cables within the Clear range, which includes Clear Sky, Clear Cygnus, Clear SE9 MP, Clear Reflection, Clear, and Clear Beyond.

Go look up their patent in the patents registry office to get further published deets or other reference materials,

- failing this, g email Josh Meredith at CARDAS and get a perspective from the source .

Thanks you for the information, it goes MUCH further than most of the Megabuck cable manufacturers (Nordost). 
 

I understand the interaction between conductor and dielectric as it mostly relates to capacitance and how that can affect the audio signal. My real issue is the differences that are claimed and cost to get there. IMO, people blow right past one of the biggest makers of commercial copper wire who has supplied to the Telecom industry and NASA, etc. where absolute fidelity is way more important than for hobbyists. That company being Belden. They will take a deep dive with you on what matters and why. I even suspect that a LOT of boutique cable companies are actually using Belden wire and twisting it in exotic ways and with dubious results.

I’m only partially a ‘measurements means everything’ person, but I do believe in the scientific method and when companies can’t explain their methodology behind product development, it says they really didn’t use one and the outcome was a stab in the dark and their results might not be able to be faithfully reproduced because they don’t even know how they got to the end result.

Thanks for listening.

Doing a deep dive into NORDOST is going to be note difficult. NORDOST technology was originally  not starting out as audio cable company ,

Nordost’s roots were in the Military, Medical and Aerospace industries. It gives the company access to the most advanced materials technologies known to man.

as you read on, I don’t have the background to properly discuss or even decode the technical terms and patented processes they describe . 

Its first audio product, the Flatline Gold speaker cable introduced in 1992, is a perfect example of this, deriving technology originally used by NASA for their space shuttle program which resulted in a cable that was extremely durable with a geometry that offered impressively low capacitance and inductance while achieving very high signal speeds.
 

For more than three decades now, Nordost has continued to push the envelope of cable design and technology, in turn improving the performance of audio systems around the world using Nordost’s patented Micro Mono-Filament technology,

https://nordost.com/downloads/multiLanguage/odin_brochure_english.pdf

Ever since the launch of the first audio products in the early 1990s, Nordost has always insisted on the highest quality, extruded FEP for use in cables’ dielectric and jacketing.

FEP has many advantages; primarily, it is the most consistent and best performing dielectric material available, with the exception of air; which is where micro mono-filament technology comes in.

The micro mono-filament technology is a process developed by Nordost to reduce the effect of the insulation material. It uses a thread of FEP which is helically wound over each highly polished conductor. A precision FEP jacket is then extruded over the thread and the conductor. A number of proprietory methods are used in this difficult and extremely precise manufacturing technique.

Now that we understand the construction of a genuine Nordost cable, it’s simply not easy to make.  We can see that the counterfeit fake Chinese cables DO NOT have the technology and manufacturing technique, and it is very costly to duplicate the same construction. Therefore, the counterfeit inferior cable can only duplicate its appearance.

Thanks again for the deep dive! I listen to Nordost cables frequently but I did not know their background in Aerospace and Defense. Maybe I picked the wrong cable manufacturer to pick on?!… lol. 
 

I know that well made and purpose built cables are expensive to make which is exactly why I’m dubious of ‘some’ of the brands making extraordinary claims because they do not have the wherewithal to do the R&D, testing and manufacturing. I am not including Cardas in my rant because I know they have been at this for a long time. 
 

Thanks again for the info.
