What was the first power cable that you noticed a difference in the sound?

@texbychoice   Jack Bybee's work as a physicist would be an example cable/circuit research for military use.

Bybee’s first commercial products emerged from Cold War-era military-industrial research. The stealthy shadow contest of nuclear submarine detection, location and evasion demanded ever-quieter circuits, lower electronic noise and greater signal-to-noise ratios. Practitioners summed up the problem as: “reducing 1/f noise, from DC to 2000hz”.  

Bybee’s technology involves exotic blends of rare-earth metals or their isotopes to reduce electronic noise in circuits. In the mid-1990s, Bybee’s AC filtering was among the first of its kind to use exotic doped materials instead of transformers or balanced power, which made it a novel concept at the time.

More examples would be these engineers who started - and continue to run - innovative audio cable companies.

Purist Audio Design – Founded by Jim Aud – EE & Physicist

From there, I earned my Electronics Engineering degree at Brescia University, and would later study Computer Science for almost two years at Westinghouse. Then I came to South Texas Nuclear, and studied what they’d call today nuclear physics. Link here.

Shunyata Research – Founded by Caelin Gabriel – Research Scientist

Caelin Gabriel is a former US military research scientist with a background in research and design of ultra-sensitive data acquisition systems.  These systems were designed to detect extremely low-level signals otherwise obscured by random noise, requiring years of intensive research into the sources and effects of signal and power-line noise interference.  Link here.

Bybee Technologies – Founded by Jack Bybee – Physicist

Jack’s science and physicist background gave him the understanding about negative effects of quantum noise. Link here.

Silversmith Audio – Founded by Jeffrey Smith – Engineer

CEO/Designer Jeffrey Smith is a Wyoming native and graduate of the United States Naval Academy with a Bachelor of Science degree in General Engineering. He also earned a Master of Science Degree, With Distinction, in Defense and Strategic Studies. Link here.

MIT Cables – Founded by Bruce Brisson – awarded 20 USPTO engineering patents.

MIT Cables founder Bruce Brisson began purposely designing audio cables in the 1970’s after encountering the sonic problems inherent in cables typical of the day. Link here.

Audioquest – Garth Powell - Sr. Director of Engineering

Formerly with Furman Power for 12 years.

It is when reading about Bybee 12 years ago that i decided to experiment with some minerals as shungite and quartz etc ... With success at my modest scale ...😊

I dont have money for costly tweaks but it does not means they dont work ...

Science is experiments, not decrees by some Pope of a technological cult faith about how and why qualia are only reducible to Maxwell equations as interpreted by some engineers ..

One of the greatest science achievements of all time come from mystics rigorous thinking by the way ... Sorry for technocratic materialists ...

life is not simplistic ... 😁

@pindac  I have read the manufacturing process for PC Triple C Wire and I'm lost as to the benefit.  If I understand it correctly, they are repeatedly working the copper to end up with all the crystals aligned.  And yet, with the OCC continuous casting process, you supposedly end up with a cable comprised of one single crystal.  Zero boundaries for the power/signal to need to navigate.  No need to compress it to remove oxygen as it's already oxygen free.  Kind of sounds like they needed to come up with a process to convince us to buy new cables?  IMHO  As an aside to this, I run Hegel amps, and questioned them directly on the best power cable to use.  They suggested using anything other than the stock cable they provided was a waste of money.  For what it's worth.  

My first "contact" with the power cord issue was buying a high power Classe amp, 25 years ago, and one of the first things in the manual was the suggestion I should purchase an upgrade power cord...I was quite angry seeing this...bought an A/C Mater Coupler a few years later, and it did sound better...and the Classe included cord was a quality cord, not a throw away...sold the A/C coupler 10 years later, for the original used price I had paid...

This is my claim to power cord fame!

One of the reasons I eliminated the power cords from my mono amps was to eliminate two electrical connection points, the wall plug and power cord male plug. Also, another reason is to remove the question about what power cords sounded best. Running each mono amp directly to it’s dedicated electrical circuit sounds better, in my opinion, then running them with power cords and wall plugs. The rest of my equipment uses 12 AWG 1 foot long power cords. As far as all power cords go I would say keep them short as possible and 14 AWG or lower. FWIW, All four of my dedicated audio lines consist of Galvanized Steel MC Metal Clad Cable 10 AWG in wall wiring. 😎
