@mbolek - a really simple cable geometry that also performs very well, uses a Ribbon geometry
- Two Teflon tubes held apart using some sort of tape
- the brown paper tape used for parcels is quite good
- The tubes should be spaced at least 1" apart for the length of the cables, for good separation
- insert the bare UP-OCC wire into the Teflon tubes and attach connectors
- allow 2"-3" at each end to get the connectors on (for interconencts)
- You could put a Mylar tube around the signal wire for improved RFI/EMI protection
It is good for Interconnects and Speaker cables
The only drawbacks with this style of cable
- there is no protection against RFI/EMI
- it is only flexible in one plain.
But it does perform very well - fast dynamics and good clarity and details.
It is basically a straight version of the DIY cables that are on the VH Audio website
