Now we are starting to get
into the more esoteric physics of an HDMI cable. For many years, mainstream
analog audio cable manufacturers talked about “Skin Effect” and how higher frequency’s
tend to migrate to the surface of a cable and that lower frequencies stayed in
the middle. As it turns out, there is
some truth to this statement. Oh, not in the analog audio domain, that is still
BS (in our opinion). However, in the
high speed world of HDMI surface silver content and the type of dielectric do
play a part in the performance of a HDMI cable.
Now just throwing a thicker cost of silver onto the copper is not the
complete answer. There must be a proper
balance. Copper provides a stable high tinsel substrate for the silver plating,
this will help the wire to keep its original length and shape which is
necessary for the higher bandwidth and speeds (see #1 & #3).
What does this have to do
with cables?
Proper balance between copper
and silver is mandatory for consistent performance.
