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

Hi there . For me every thing is simple. Top line speakers as well as amp ,power amp, preamp, cables and ofcours most expensive on entire world . And no question, no more arguments . It must sound good. I might invent something exceptional something extremely good sounding, but who is going to admire it , I got no name. We already have a gurus who are on the top. I should maybe write, money talks as simple. Thank you , nothing to argue about.

Poor wording on my part.  No the cables do not calculate.  The company measures all of your components' parameters and the company builds a cable with a network that that takes all of those factors into account.  Now your search is over.  Sorry for the ambiguity.

The speaker's 8 ohms is not a part of this calculation.

Your first par. adds the speaker impedance with the cable resistance (like adding bananas with apples!). The concept is wrong.
The speaker's cables resistance is not part of the load (speakers). They are an extension of the amplifier, just as I claimed before.

Your second par. is also wrong! DF is always related to 8 ohms (@1kHz), even if the actual speaker to connected is other (4 ohms or higher than 8 ohms). It is a fix number = 8.

In overall, your way doesn't fit the actual relations, nor explain what different cables sound different. As if you would be right, all cables would sound the same.

Silver has a better conductivity than cooper by 9%. It's cost 94 times more. There is no way you can get a silver wire for $7/feet. Silver's melting point is close to the cooper (about 1,000 deg. C). very hard to work with.

Not the elements inside or other do the difference but the overall resistance.
That could be achieved in other ways too, without using exotic materials.
For the distance, I use two different cables (red and black) that are never in parallel.
All your say is not in line, as I excused non coil speakers from this conversation, and yours are ribbons. (Magnepan MG IIIa’s).

Sorry that all your money could't buy you some knowladge.

Skin effect:

What about the wires inside the speaker boxes or inside the amplifier? They are in that loop of speaker's cables. 

·         Speaker manufacturer provide FR (Frequency Response) data that was measured in test.

·         Amplifier manufacturer provide FR data that was measured in test as well as calculated.

·         The above data is often reviewed and proved by magazines and web sites. They are true.

None takes measurements to tangles the skin effect issue. Speaker cable manufacturer's that never provides any piece of technical data, all the sudden do pay special attention to the skin effect. Why?

The other part is that what the FR of skin effect is telling us, that a 0 awg cable that has a 150A current capacity, is good up to 250Hz@150A. this cable can still pass way more current at 20kHz than a thin cable. A cable of 19 AWG van pass 21kHz @ 1.8A. A 0 awg can do that too!

You say: "Cables are VERY low impedance in the audio spectrum; certainly lower than the output impedance of the vast majority of amps out there". Absolutly incorrect. Most power amplifiers out there are class A/B and have DF of 200 and above. 

Most speaker cables are 12-14 AWG and are 8'-24' long. Your say  VERY low impedance shall get figures. you will find out that the figures are no more that low vs. the output resistance of amplifers, when using 8 ohms / DF.
