What is the best cable for speakers

Let us analyze it from a technical point of view. As we all know, a good speaker cable needs low resistance. However, a wire that is too thin will obviously not have a good effect, because the resistance of a thin wire is large, more power will be consumed on the resistance of the wire, and the loss is particularly serious. At the same time, although a wire that is too thick has low resistance, it will waste materials and money. It is generally considered that the loss (insertion loss) on the wire is tolerable below 0.5dB. Second, in the circuit from the output of the power amplifier to the speaker, the impedance of the speaker cable, the length of the wire, and the thickness of the wire are all important. The general method is to calculate the thickness of the wire based on the length of the wire and the impedance of the speaker cable. There are many kinds of wire on the market, and the prices vary greatly. We can make a difference in the structure, materials and appearance of the wire rods. Fever grade speak cables are made of higher purity ES-OCC (Oxygen Single Crystal Copper) or OFEC (Oxygen Free Electrolytic Copper), which has the characteristics of flexibility, tensile strength and bending resistance, while counterfeit wires all use ordinary copper thin wires as conductor materials.
