Do all audio & speaker cables sound the same?

The TechZone looks at the esoteric world of high end audio cable.

The very basic reason why audio cables are important is because they change the signal going through them. There are two different, fundamental ways that an audio cable can change the signal. The cable itself can change the signal, or the cable can allow outside sources of energy to change the signal. In order to understand how these two situations can occur, some basic background electrical knowledge is needed. Read on over here.
