Construction my own RCA IC
This is my final construct of RCA IC for my DAC and AMP.
Upon encouragement from Timber, i proceeded with the order of Neutrik RCA heads.

So i figured it would be good enough without having to spend too much and focus on the cable itself.
Having soldering iron and solders gave me motivation to try without having to spend extra.
Construction of RCA Cable
For my cable selection, I had a length of spare marine cable around. It is 2.5 mm2 cable.
It is approximately AWG 13 for this size.
 |
| Per core 2.5 mm2. Solid copper core. Per core is d=0.7 mm x 6 strands. |
The OD of the wire is 3.5mm with insulation PVC grade ST2.
The second layer is a flexible OD6xID4mm Polyurethane (PU) Air Tubing
The copper sheath is taken from my spare coaxial cable and it fits well on the blue PU air tubing.
Got the 2:1 shrink tube from audio store as well as extra RCA adapters as my order has not yet arrived.
The adapter is for small gauge wires only. To overcome my thick 7.5mm outer diameter, I had to remove the plastic insert.
To adjust the slack between the cable and adapter, i added another short length of shrink to beef up the thickness.
My first time soldering. Well, sacrificed two adapters while learning where to solder. The thick wire gauge is a challenge to work with.
The finished product. 10" length 13AWG interconnects.
Yes, i know it is an over-kill with such a short & thick cable.

| The resistance of DIY cable is 0.000 ohm |
