Neutral electronics are a farce...

Al,
The idea of relative neutrality is as you say, self evident.  As my system has improved over the years,  very subtle incremental musical information is definitely more distinct, the very fine tooth comb analogy. Contrast becomes more stark and apparent with simple system changes. This would suggest less sonic character imposition from the system components  . Absolute neutrality  is different  matter. 
Charles, 

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. The reason ELF works is actually because the transmit power is 1M watts and because the preamps on the receive side are extremely sensitive. But getting back to my real point for just a sec, shielding protects the conductor from external EMI/RFI but not from it’s own induced magnetic field. That’s why I said cables and power cords shoot themselves in the foot. End of argument.

^^ Do you really believe that?? Here’s another link from Wikipedia:

https://en.wikipedia.org/wiki/Radio_propagation
-wherein we find this text, pretty much the same as they teach in school:

In free space, all electromagnetic waves (radio, light, X-rays, etc.) obey the inverse-square law which states that the power density of an electromagnetic wave is proportional to the inverse of the square of the distance from a point source[5]

The math is shown on the Wiki page. If you click on the inverse-square law link above, you will see why this is so.

If what you 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!
