There is no magic to it, but there are many other factors.  A couple: triboelectric effects, dielectric effects, etc.  If one only thinks in simplistic terms at the most basic level (L, C, & R) one will usually get simplistic results.

Even makers of general bulk audio cable like Belden and Mogami take these effects into consideration.  What about shielding? L, C, & R do not even take into account the effects and methods of shielding.

 

Yep and we even know how to test for things like triboelectric noise.

 

You should know better btw and I think you are being purposefully dishonest in regards to the title off the thread.

 

If I'm doing a null test and I take cable A and suspend it across an open span and hang a weight and let it loose I'm going to generate energy. That's going to travel across and it will show in the null test.

At the risk of oversimplifying things ? a null test will eliminate all differences between the devices being compared.

 

Actually the null test will SHOW differences if they are there.
