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

Mr.  kosst_amojan

We will see when the first guys here will return after giving it a shot and share with us their impression. A little patient and we are there.

I've seen what happened with some friends who listened, didn't doubted me for a minute, and ended up very happy.

I'm assuming that the spade comments are for my benefit? If so, thanks.

I can get the cable unterminated and use a cable reducer to drop the cable down to 4awg. Once it's 4awg it'll fit in a banana plug. Or I can use a distribution block to join 0awg and 4awg and run a very short length of 4awg direct to the terminal on both ends. Would either of those approaches work?

What a few suckers say about your nonsense hardly constitutes proof. There's people around here buying spots and clocks and swearing they make a difference. You said you had a perfect calculation. You don't. You can't prove you do. 

Mr. kosst_amojan

What is it you have about speaker cables? Nothing. 

It's all against, right?
What is it that you scrawl out under your stone all the sudden after six pages of this thread is going on?

What firm is that supporting you, that got all the sudden scared from being exposed?

At the time you are shouting all over NO, you better come up with something to explain this speaker cable mystery. In other word, please say what YES.

This is the pasta party. Not the "Antipasti" party, which is a small pasta with a negative attitude. This is mirror time.

What "buying spots and clocks" has to do with this? You found out that all the rest, like directional cables, burn in, cryogenic treat and skin effect were un useful  so you dig the buying spots and clocks In a forgotten drawer, never yet used with speaker cables, maybe it will work now?

Mr. conradnash
The thicker wire to fit a banana plug I know of, is 8 AWG. 
You better check that the wires / cables are sold to you, are what they claim they are. I wrote on some car cable kit (US made) that were fake in size! they claimed a 4 AWG taht turned out to be an 8 AWG...
Try to keep the transaction between the thick cabe (4 AWG or 0 AWG), to the binding post as shord and of the the best qality.
Do not trust poor connections or lose once. Some of you here have too good equipment to risk it with a $100 DIY advanture.
