If the cable has a arrow, that arrow is usually included only for convenience. (Arrow points from source to loudspeaker). It's merely a suggestion in all but THE most esoteric designs. Generally once a cable is broken-in in one direction, it needs to be broken-in again if you try to use in the other direction. So I'd say just pick an orientation and stick with it going forward.
I'm sure some nay-sayers will chime in telling us the futility of believing cables are directional once broken-in (or in fact they need burn-in at all). Use your ears.
