The short RCA cables are made using Supra Trico wire (the core is stranded in case you are wondering) and HGA LOK Silver Point plugs.
The long RCA cables are also made with Trico wire but have Eichmann Silver Bullet plugs.
Disregard the short one for now.
This picture shows a now yet sleeved RCA to 4-pin XLR adapter, I use it to connect my K240DF's to my Aragon 18k.
It is made from braided Mogami w3080 wires, WBT 0114 plugs and a Neutrik NC4FX-BAG silver plated XLR.
Also shown in this pic is my SPDIF cable, it is made from Supra Trico with the outer jacket and shield removed, it still has the inner silver plated shield though, WBT 0114 plugs.

And lastly my completely rebuilt K240DF's with new plastics and drivers, basically a new K240DF.
Cabled using braided Magami w3080 wires and a Neutrik NC4MX-BAG XLR.
My RCA to XLR adapter has the same finish as this cable.
