There are two people that want to build my speaker cable, so I post it here how to make it. I use any 16 gauge speaker cables from ebay, I just get the cheapest of the cheap ones. Here is an example of one I found:

You can use others, I pick RED/BLACK for easy to see. You don't need to buy pure copper or oxygen free copper stuffs, you'd just wasting money. I use copper clad ( copper plated aluminum wires) ones because it's the cheapest.
For single banana connector, I use this from Amazon:

For Twin banana connectors, I use this from Amazon

Everything is the cheapest ones.
1) Cut 5 pairs of the 16 gauge speaker cable to the length you desired PLUS 12 INCHES. The extra 10" is for shrinking when twisting the cables and for cut to match length.
2) Strip 1" of the insulation off one end of the cables, take all 5 of the stripped Red wires and twist them together and fasten to the RED post of the Twin Banana connector.
3) Twist all 5 of the stripped Black wires together and fasten to the BLACK post of the same Twin Banana connector. Now you have one end of the cables all tied to the Twin banana connector. See Picture 1.
4) Fasten the Twin banana connector somewhere that is secure. I use a vice, but you can tie to the door knob. Important thing is it has to be secure as you have to pull and tuck the cable. Make sure it will not slip off.
5) Pull all 5 pairs to make sure none of them have slack, they all have to be same length. After you get tuck them tight, either tie a knob at the other end, or tape all the ends together to prevent it from slipping. I use TIE-WRAP to hold them together. Now it's ready to be twisted.
6) If you have an electric drill, that would make the next step very easy. I just fit all 5 cables into the drill chuck and tighter the chuck to grab onto the cable ( has to be tight and not slipping). Then I pull the 5 cables tight with the drill and start spinning the drill CLOCK-WISE. Make sure you pull the drill tight and let it turn. When you feel the cable shorten about 8inches, you should have a good twist along the length of the cable. You should be ok. Put the drill on the floor and pull it tight enough to prevent the cable from self twisting.
7) If you don't have a drill. Tie something heavy on the other end and start hand twisting. Twist until you get a good twist. Rest the heavy weight on the floor and pull the cable tight to prevent it from self twisting along the length.
8) Take electrical tape and wrap it COUNTER-CLOCK-WISE starting from the Twin banana connector end. Pull the cable tight with one hand while wrapping the electrical cable. Make sure the cable is straight while you are wrapping the electrical tape. The electrical tape is wound in opposite direction of the cable, will prevent the cable from un-twisting all the way. See Picture 3.
9) Wrap the electrical tape all the way to the other end. You finish the difficult part. Last step is to put on the connector on the other end and you are done. Make sure you peel the insulation 1" off also. See Picture 2.
After you are done, you can cut off the excess copper wires sticking out of the banana connector. Make sure you recheck the screw on the banana connectors, it will get loose a little in a day or two. Tighten it again.
One word of warning, this cable is about 2500pF capacitance, there will be amps that cannot handle even 2500pF. My Nakamichi PA-7 is one of those. This is still only about half of the Kimber Kables. That's the reason a lot of amps cannot use Kimber Kables. Mine is the water down CHEAP version of Kimber Kable. I am pretty sure if the amp can handle the Kimber Kables, it should sound better than my cable. But mine is CHEAP and can easily be DIY.
There is engineering theory behind this. I explained in post
#2 of this thread if anyone care to know the theory behind using 5 pairs of smaller wires. Also twisting will further reduce the inductance. All explained in post
