You can buy expensive cables, or make them. Sonically, the expensive might sound 1-2% better. You are really paying for the build and quality of the wire. I just make my own buying OFC wires and stringing them through a pvc tube. They sound great and very heavy duty.
Items Used: 10awg OFC wires $40, Vborg plugs $60, braided sleeving $10, shrink tubing $15
