What do the arrows mean on my cable?

Arrows indicate signal direction which is from source to preamp if present to amp. Usually used with analog signals not digital. Does it matter? Try it and see. If the arrows are there best to follow directions if you must choose.

Attached is an image of a typical directional RCA cable (this example is from World’s Best Cables WBC).  The idea here is that the shield collects any noise before it gets to the inner conductors. The shield is only connected at the source end, such as a preamp, and is not connected at the receiving end, such as an amplifier.  This way the shield  noise is not allowed to enter the amplifier.
