Somewhat along these lines John?

No. They show a thin inner conductor with thick insulation.

** Try reading the text.

There is no "insulation"used.

The black layer is a carbon filled plastic = a conductor.


If it conducts, it barely conducts. Nearly all the current will flow
through the copper. So it may as well be an insulator.


"In keeping with the fundamentals of HF-technology the impedance of
any conductor will rise dramatically in the bass region..."

is standard audio pseudo-scientific nonsense.




Impedance
goes as the log of D/d, where D is the diameter of the shield and d is
the diameter of the inner conductor. So to make D/d approach 1 (and
impedance approach zero) the insulation must be as thin as possible
(which adds capacitance, of course.)


** What if there is a conductive layer used ?

See above.




The impedance graphs and text on the cited web page are made-up lies.


** You have done tests on the stuff - right ??

No, but the reference curves, the ones above the miracle cable, are
plain silly.

There's no way a dinky construction like this is going to have Zo of
10 ohms.




But I suppose the wilder the lies,


** Err - like your ones here ??

Audio doesn't really matter anyhow.


** Only to the deaf and the daft.


It's only music. I doesn't matter.
