Thin cables do break easily if accidentaly a node is in it. Also, they are not shielded against interference. Thicker cables mostly do have a shield, and they are tougher they won’t break in any circumstances.
In the connectors a lot of difference in quality is seen too. On the cheapest cables, the connectors are always melted to it. In the more expensive cables is often possible to remove/change the connector.
Some connectors do have barbs in it.If someone pulls on the cable, the force is being directed to the outside of the cable instead of the solder points and the cables core.
A long cable has a negative influence on the sound quality. This will be audible from about six meters. Although the loss is minmale, it is advisable not to use cables that are meters longer than needed.
