I need help on directionality of speaker cables

I always place arrows or use another identifying mark to show the direction in which the signal flows [source to preamp to amp to speakers].

In case you ever disconnect your cables, you won't have to worry about another "burn-in". And if you use XLR connections, they will only go one way.

Geez, Bob P., you should be a lawyer :-) You caught me on a technicality, but you are right. Perhaps I should have said the arrows point to the next level up in the audio chain [source to speakers].

And might I urge you to also become a member? Like Belushi said in ANIMAL HOUSE, "...it don't cost nothin'."
