Audiophile nutters is all I can say. Could be worse. At least this cable is in the signal path. You can get insanely expensive wooden knobs with ultra secret audiophile grade lacquer that alledgely makes your amp sound better.

There is some stupidly expensive amp which the main feature is that it doesn't contain many components. Its just a single integrated amp chip with a couple datasheet spec components but less = more it seems.
