Before I moved out to California I worked as a home theater installer for Magnolia Home Theater and the salesmen there would try to sell expensive premium cables to each customer that they helped. A lot of the premium cable manufacturers would claim extra features like EMI (electromagnetic interference) shielding, or Uni directional electricity flow, which by the way is a load of garbage. The biggest problem with these premium cables is that most people are not educated on what cables are made of or how they work.
Most cables are made out of wrapped pairs of wires, which you can imagine can’t really vary that much from one cable to the next. Now each of these wires will be wrapped in some sort of insulation that prevents them from touching each other when they’re inside the main cable. This is where some cables might have a thicker insulation than others, but they are still basically the same wire. Now there is a way that some cables will differ from others in that they will have a shielding wrapped around them to protect from electromagnetic interference, which is static that comes from electrical components.
Recently I received an HDMI cable from
If you were to cut open premium cables and discount cables you’d find that inside they are almost identical. The only thing that really separates premium from discount cables are the type of connector on the end. And that can only go so far as HDMI cables all have the same type of connector.
