As posted elsewhere by someone other then me “I am contentious that we are all cable experts and the ones we have made are better than anything in the market and your mates one too!
I wanted to see if I could make a mechanical cable spacer and see how it worked to reduce inductance and capacitance. The spacers are Carbon fibre nylon. Many different configurations tried and this is what i landed on. A really difficult material to print at this size but gives good flexibility and very strong.
The modular approach means I can make cables of any length now and get a decent amount of wire into the disc for a good overall conductor diameter. These cables have 3 x 1.5mm OCC N7 copper conductors. I used soem cheap aliexpress xlr plugs to just try.
The shield is pure copper and earthed at the preamp.
Well the results from is what I can hear a good XLR. The resistance is 0.0198 Ohms and Capacitance of 84pF over 2.2 meters.
Would be interested to understand where this cable performs in terms of its measurements. Please cold you all take a look and if you have some good cables and able to measure accurately with decent instruments and let me know how these cables stack”

Spacing the two conductors will reduce capacitance but increase inductance!
In a balanced interconnect system it will greatly increase to susceptibility to interference.
In an AC power cord it will increase the transmission of noise.
In a speaker cable it may reduce the very high frequency response.
