Directional interconnect cables

Well, I'm convinced now.... I'm going to turn my throttle CABLES around. My HOG should run alot better......

LOL......

Showing my ignorance here, but if analog audio signals are AC, how is there any directionality at all apart from shielding ground?

To try to get back to the OP's original question. It's not that the wire itself is directional. It's the assembly of the cable as a whole. Some cables have the shield terminated at both ends. Non-directional IMO. Others, have the shield terminated only at one end. In this case, again IMO, the end(s) with the shield termintated should connect to the pre-amp. This will create a single point grounding scheme.

Of course, as some others have said, connect the cables per the manufacturer’s recommendations, and enjoy the music.

I don't understand either but people hear what they hear and believe what they believe. The one thing I've learned is, apparently, the directional arrows don't always mean that cables should be installed in the direction of music flow which is intuitive but, instead point to the grounded connection. I never knew that and don't consider it intuitive.

Carl109 nailed it. Electrons displace in both directions, that's how the electrical signal is propogated throught the wire; they have to move in both directions to send the AC (i.e. music containing) signal.

Hey, if our speakers and eardrums had to flow in one direction, well that wouldn't work for very long.
