No one actually knows how to lculate what speaker cable they need

Keppertup: Well I am quite familiar with the ladder line concept from Ham Radio RF work.  I would lean to it being hard to hear differences at audo but given the affordable nature and hands on fun (kind of like op amp rolling)I am leaning to trying it but it will likely take a while to get to and have the team together to do my blind test hook up for me.I like that it has BIG parameter changes vs 12 g copper zip.

There is so much pseudo science and 
engineering as to be a prototype for "whacko audiophilia" and many smiles so thanks. But I did want to put in a genuine admiration for Keppertup's hands on experiments based on straightforward parameter changes and rational money. I might look for some of that jewelers wire my own self.
I have yet find better than #12 copper (12 foot lengths) for my system, that I compare to live unamplified acoustic instrument sound that I know well, because I play it. But that is just me.

ThePigdog: Think of it as Gabriel Marquez meets Hunter Thompson. Then it becomes art. Found art.

For folks really trying to understand this stuff, you could do a lot worse than googling Waldo Nell The science behing speaker wire. 
He discusses real engineering with real math.

This is getting good. Like pro wrestling at its best worst.

This is NOT in any way addressed to GK. I understand you have your own relationship to engineering and unique undertandings.
b4icu you seem to have a partial handle on some aspects of signal transmission physics, perhaps this link might be partly useful

If not, no problem. Most engineers understand that damping factor is swamped by the nature of driver, uniformly low amp output impedance, little effected by typical lengths of speaker wire.
Best wishes.

OK I'm sure you guys are right. Off to play some music.
