Length of speaker cables

Mr. dannad
From study of the cables relation to load (speakers) and drive (Amp),
My analysis point of view is that I need to look into the Amp's output through the speaker cables.
As so, the speakers are not a part of it. It proved to be true, when I used very easy speakers to drive (Klipsch Forte-II) with 99dB/w/m SPL with a 250W Carver Amp.
Or a B&W 802 D, with a 250W PASS LAB. On both, speakers were ignored (as my analysis suggests), cables calculated, tested and proven to be correct.
The definition of DF is for pure resistive values. The cables are part of it.
A thick copper wire has such a low resistance, that the other C and L are irrelevant. So why AC?

Well you can come up with a theory, but it also need to work in reality. 
Mine do.
What about yours?

Answer me: Did you ever tried it?

Mr. dannad

I need to show you nothing.
Parasitic capacitance? My cables are singles. To have capacitance you need two cables (plates). Parasitic capacitance do not apply for my solution. 
You didn't answer my question! 
when you do, we can continue. 

Mr. dannad

1. I was not answered properly. So till then, you can post questions...for others. I’m not in your game.

2. The cable’s parameter to go with, is not Fr. nor C and L.
3. Even though you wish, I’m not going to play your game.
4. My cables are not 5mm apart. they can be at any distance as they are separate. I have 4 cables for 2 speakers. 
they are individual. I've told you that already and you do not listen, or ignore it deliberately.
