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

Mr. kalali

The thick cable are separates. As so, no capacitance is developed.
Capacitance is defined as the dielectric value developed between two metal plates at a steady distance...
The cables are meant to be as short as possible. There are no extra wire on the floor that get coiled to create inductance.
The Z of such a cable, if any, is negligible. Because the R is so low, capacitance or inductance are negligible.

Thank for your concern.

My solution, as seen on one of my posts, was to use a short 8 AWG agent wire, between the banana plug and the thick cable.
It is also good for the strain relief on the contact point of the cable with the binding posts.

Even if I would find a banana plug that could take a 0 AWG cable, I doubt it if I would use it.

Keep in mind that it is difficult to work with a 0 AWG cable. It is very different then the ordinary 12-14 AWG cables.

Don't twist the red and black cables.

I like the idea of direct connection much better with high quality connectors. The resulting sound will be better. The idea of splitting the cable into two equal portions and terminating with a spade and banana for direct connection to the binding post is a good option. It reduces the strain on each connector also. The wire link I gave is for very finely stranded copper (thousands) with is very flexible and easier to work with. It is pure copper, not copper clad aluminum which would not sound as good.

I ordered mine and they came in slightly cheaper than I was expecting, £125. They're being cut and crimped this weekend and will be shipped to me on Monday, I should have them hooked up at the end of the week so I'll report back with images.

May I ask from who and what did you order? Fully assembled? Can you provide a link and how they will be terminated? Thanks.
