Why high-end cable manufacturers don't post measurements?

For the sake of this endless argument, what is your explanation to the difference in sound with different speaker cables

For example Take a stranded copper cable of 0awg and one of 12awg running 10 feet connected to any amp with a DF >300 and a nominal 8 Ohm speaker and there is no difference in sound. 

Mr. B4icu it's not relevant what distance the wire and DF of amp without taking into account the impedance swing of the speakers. You keep on pushing battery cables and I'll stick to reality. 

What's the deal with this goofball and car battery cables for speaker wire. 
My amplifier DF is >10000
My wire distance is 4000 feet. What guage do you reccomend,  777MCM ?

you can get it in 0, 00, 000 and 0000 thicknesses.

I prefer MCM / kcmil guage for truly reference cables that are good up to a mile. 

My speaker cables aren't hi end so I was able to find specs on them.

the Speakers are insignificunt

??? You can't be serious. 😳
