One thing that confuses me about the audiophile cable market is I’d have thought the set-up costs were huge unless you are simply printing a brandname on a commonly available design from an existing major cable supplier, e.g. IIRC both Linn K20 and Naim A4 speaker cable was the same stock BICC stuff with a different colour sleeve and the brandnane stamped in.
In a declining market such as two-channel audio it would surely be prohibitively expensive to do much more than this below say vdH or Kimber level who have been well established for decades. Far easier for someone to knock out a new amp, pair of speakers or whatever as you can get boards stamped out by PCBWay, it is easy to find companies who will CNC small batches of cases/cabs, and everything else can be bought off the shelf. A genuinely new cable would need a lot of real investment, surely?
