@captbeaver - the Helix cables take three skills, other than cutting and stripping wires and using a screw driver...
1. use of a variable speed drill - i.e. at different speeds
2. solder a reasonable joint (but that is only mandatory for the Interconnect cables)
3. Know how to crimp a spade connector onto a wire
Using the heatshrink or expandable sleaving is pretty intuitive, but try a test piece first.
Screw-clamp bananas plugs can replace the soldered Banana connectors on the speaker cables is you prefer
You do not have to solder the spades on the power cables either, that is just my preference. Crimping will suffice
They probably look more complicated than they really are, but you should probably practice winding the spiral and spacing it using an old piece of wire first - I used some old Romex house wire first
With the actual wire identified on my web site holds the Helix spiral shape nicely. Then once the live wire is inserted into the helix spiral, you simply stretch it out evenly to the length of the live wire. If you stretch it too far simply compress the coil and start over
For the power cables, before stretching the neutral and the ground wires I attach the mains plug, because it holds the coils together.
If there is an area on my web site you feel requires more explanation let me know and I may add more pictures or text
