Concepts
Cable Quality
The best signal cables objectively are those with the lowest signal resistance. Factors that affect signal
resistance include wire gauge, cable shielding quality, and cable connector quality. However, the same
materials and engineering designs that reduce signal resistance add to the cost of manufacturing. This
added cost is passed along to a consumer. So, it is useful to understand when signal resistance is not
relevant. Knowing this can help you to manage and reduce expenses without necessarily lowering
your standards. High cost is not inevitable. Nor is it proof of high quality. Sometimes, in fact, high
quality (low signal resistance) is irrelevant.
Even mediocre signal cables are sometimes sufficient, and such cables are often very affordable.
