Please allow me to put on my electronics engineering hat a moment.  How 
does one
line up copper?  I need to see the physics of copper molecules orienting
themselves as the liquid metal cools into wire.  Someone's pulling your 
Lines up indeed.

And how does passing a signal through wire teach it anything?  There is no
physics to this marketing BS.

Yes, impurities change the resistance of copper wire.  And that's it.  
drop will result.  But wire is so pure that, the difference between 100% 
copper and the worst wire you ever bought will not cause a perceptible 
change in
amplitude of the signal it passes.  And frequency response is unaffected.
