Dear David,
unfortunately our marketing department doesn't like to offend people who
believe in the "burn in" and directionality theory of speaker cables. If
you subscribe to these theories, you may choose to arrange the QED Original
cable so that the writing points from the amplifier, towards the the
speaker.
If, like me, you don't believe a piece of copper can behave like a diode,
you may safely ignore the advice!
Sorry to have worried you for the sake of political correctness,
Yours sincerely

I think that answers the question nicely. just worry about polarity (+ve to +ve and -ve to -ve) and you're sorted.
