I use this duchess double crown cable at home only but single siltech duchess crown not very heavy. Before both connectors (2 pins and 3.5mm)need to change on my own.....i remember several hundred is a must but forget the exact price
If use normal method to weld the wires siltech solder will becomes less bass....beside WBT solder u can try audionote solder as i tried severals before is most near originated siltech duchess crown signature sound
I tried 5 x duchess crown cable before (i still have 3 x duchess crown cables at home) hope can help Myself兄
