If we're using the vodka analogy. Vodka is the metal of the cable: the copper/aluminum/gold. Yes, you can have really bad quality metal, but it's practically unheard of given how easy it is to make good enough quality metal for cables.

What matters more is the rest of the ingredients mixed with vodka to make the cocktail (which is the connectors, insulation, and shielding of the cable). If those are good, they'll easily mask the common issues with cables. If those are bad, it doesn't matter how good your vodka/cable metal is.
