It might be old hat for some, but it's not necessarily so for everyone.
Not all cables can pass all frequencies precisely (no mater what the level) without any timing delays or transient loss. That's especially true for higher powered situations such as speaker cables.
Manufacturers play on this fact and produce exotic products that are designed to extract massive sums from gullible audiophiles.
That's why this discussion is important and shouldn't dismissed as repetitive.
How does cable construction affect sonic character?
I think this altered cartoon expresses the gap between cable skeptics and believers. No one knows what happens in the brain, the machinery between the engineered cable and the subjective experience (expressed in language). It's something miraculous -- or, for skeptics -- it's nothing.
