pro snake 14661 NL4 Cable 4 Pin 20m

Purchased this 20m cable + 2 Neutrik connectors in order to make 2 pcs 10m cables for my setup.

=> Which means that I have had the pleasure of cutting the cable up and take a look inside. :)

The outer sleeve is thick and the cable feels very heavy.
As expected there's 4 stranded conductors in Red/White & Blue/Black.
The inner cables feels like silicone, but I could be wrong about this.
I'm guessing that there's more than 200 individual strands in each!
The 4 wires is arranged around a piece of soft loosely wound rope ( maybe cotton? ) filled with a powder that feels like corn starch.
I guess this reduces friction / adds flexibility.

Overall this cable ( actually two cables now ) looks very promising.
