I think the crucial part for any cable is the pureness of the copper and adequate gauge for the length of the run. The hyperbole that has been created in the wire arena is purely market propaganda that seems to have created a nice market. When many dollars or hours are spent I'm sure the listener is straining his hearing in order to justify the effort or cost; in doing so will probably hear things they did not pay attention to before. You can't fool scientific double blind tests. Many have been done and listeners repeatedly have failed to tell differences between cables.
Save your money and buy some music.
