Neutral electronics are a farce...

What does all that have to do with the price of spinach? The shielding in cables protects the cables from external radio frequencies but does nothing to protect the audio signal from the induced magnetic field. And the reason is because the induced magnetic field is a different issue and requires a different solution. It's name is high permeability.  But I repeat myself. You guys can’t seem to see the forest for the trees. And for transformers the (induced) magnetic field is an even bigger issue. And manufacturers apparently do precious little about it from what I can see. It's almost like they're oblivious. The electron tubes are usually sitting right out in front on those big old transformers. Like sitting ducks.

Incorrect statements have a lot to do with credibility.  Credibility has to do with most everything.  It's not rocket science.

Geoff, in case it wasn't clear my last post was in direct response to your contention that:

Radio waves do not follow the inverse square law like magnetic fields. If they did we would be unable to talk to astronauts on the moon or to send transmissions out into the galaxy you know SETI and all that. Radio waves don’t attenuate in vacuum of space and the only reason they attenuate in free space of Earth’s atmosphere is because of losses due to absorption and scattering....

If what you [Atmasphere] are attempting to claim was actually true they would need repeaters every twenty feet as opposed to every 25 miles or whatever. When transmitting to a satellite at 23K miles there are no repeaters! Hel-loo!

I did not and do not express any opinion about the effectiveness of shielding with respect to magnetic fields.  I don't feel I can comment on that question in a knowledgeable manner without devoting more time to studying it than I care to devote.

Thanx for the comic relief, Mopman but would you try to refrain from using my lines?
