What's the real scoop on cable "signal direction"
I've always wondered this, if you actually read the cable instructions or read the small print on the cables themselves, you'll often find an arrow or instructions telling you to run the signal path (ie from CD player to pre-amp or receiver) in a certain direction.
What's the real deal with this, does it really make a difference which end of a cable you plug into the source? If so why? What happens if you run it in reverse? Or is this just yet another goofy marketing ploy?
Thanks.
P.S. No flame wars, please :)
