No money - Audio is AC. Your interconect cables carry only AC. If there is anything but AC on your cables then something is defective. Now, in order to cary AC your cables have to do just as good a job when electrons go from the cd player to the preamp as when the electrons go from the preamp to the cd player. If the electrons are treated differently by the cable based on which direction they are going, it would make a terrible mess of the signal. So, if you have ever heard a difference based on which direction your cables arrows were pointing, you can be certain it was your imagination.
