I don't think anyone will argue, for instance, that capacitance will affect sound. However, it's not going to cost a lot of money to simply find a lower or higher capacitance cable.
Where people start to wonder what is going on is when the cable makers start to use a lot of other "science" to explain why you should spend thousands of dollars on their product. R&D costs something,ads and small part manufacture are issues for making small quanities of anything (though they don't have machining costs in cable manufacturing generally) but wire is fairly cheap.
The very idea that 30K speaker cables exist scares a lot of people.
