Why not buy low cost cables?

From the exterior appearance cables have basic components that can be deceptively basic: Input, output, and a line between both. But don’t let the simplicity fool you. For a variety of reasons, mostly having to do with materials and construction, not all cables perform or sound the same.

At the very least you should require the following for your cables: durability and dependability. A cable should last a "lifetime" (which equals about three years of heavy use, although many report 5-10 years of steady use without any failure). Most low cost cables do not offer either of these benefits and in the long run, you will spend more because of the time, effort, and money spent on replacements.
