The amazing fallacy of High End stuff...

And copper wire is copper wire.....


Yet.... the hype:


  • PSC (Perfect-Surface Copper) / PSC+ conductors
  • Counter-spiral HyperLitz geometry
  • Multi-position carbon-based noise-dissipation and crosstalk-dissipation systems
  • Cold-welded connectors


Naturally, all that fancy jazz talk will impress people that don't know a thing about electrical products, or physics or science.

Agreed... For all intents and purposes, you could use a power cable made from steel and not notice much of a difference unless you were powering a heater or something 🙂 Barbed wire comes to mind...
 
A case of smooth marketing? 😉


I'm sure the electrical atoms and molecules jiggling and vibrating around in my worthless old zip cords would thank me to give them a "pure surface" copper to play in.
And my audio systems would sound like mega-buck esoteric wonders of the universe.
Patsy Cline herself would probably come back to life and sing for me, and then make me a nice drinkie. :yikes:

You're ignoring the effect of perfect surface copper on the improved electron flow in which at high frequencies most current flows in the outer skin. The perfect surface copper surely must assist laminar flow whereas in other cable it is turbulent.

Oh no, I'm not ignoring anything that's relevant to audio systems.


The "skin effect" you mention is a documented real thing - at microwave frequencies.
And certainly has no relevant issue at 60Hz or even 20-20kHz.
I'm sure you posted that info as an amusing addition to this thread.
 
Here's some skin effect science from the University of St Andrews (see attachment):

The broken line shows what we might expect when using wires of ‘Litz’ construction with a fill factor approaching unity. The solid line shows what we might expect from either a solid wire or a multistranded wire of closely packed thin strands.
Note how tiny the power losses are.

Yes, another misconception of an electronic effect that takes place at very high frequencies. Yet another one, is the pinch effect which requires huge currents to flow to manifest itself. However, at such currents wires would melt.
