Silver wire is best.
Usually, the material of speaker wires produced in Japan is mainly "pure copper" wire, while European and American countries mainly use "processed" wire.
Copper wire: It is also made of copper metal as raw material and is relatively affordable. It is also a very common type of speaker wire on the market. For copper wires, it is best to choose oxygen-free copper, long-grain copper or single-crystal copper.
Copper alloy: It is an alloy of copper, silver, and zinc, commonly known as brass. Wires made of this conductor material are rare in daily applications. The audio signal transmitted by copper alloy has the same timbre as that of traditional copper. There is a big difference between the lines and they can be used in some equipment but not in others.
Generally speaking, this kind of wire is suitable for equipment that requires high-pitched sounds. It is currently more popular among foreign mid-to-high-end wires and has excellent results in home speaker systems with short transmission distances.
Carbon fiber: This kind of speaker wire has high strength and excellent anti-aging, anti-oxidation and tensile properties. However, it should be noted that carbon fiber wire is not suitable for equipment with low output impedance and long-distance transmission. It is not applicable to professional venues.
The current signal flowing in it is much larger than the video cable and audio cable mentioned above. Because the signal amplitude is very large, this type of cable often does not have a shielding layer. For this kind of cable, the key is to reduce its resistance. , because the output impedance of modern power amplifiers is very low, the requirements for speaker cables also increase.
