Usually. Sometimes the stock cable is really cumbersome and/or ugly and you really just want to put a nicer cable on your headphones (for me, HD800). Then there are special cases like the Fidelio X1 which have extremely poorly made wires attached to a low-z transducers (which causes impedance matching problems and issues with bass control). But generally, high end cables are purely snake oil. Basically a necklace for your headphones.
