So you think wire conductors in cables are directional? Think again...

Did the OP get bored? What happened to him?

Banned?

He joined in April 2021 and already has in excess of 250 posts. It’s probably just one of the resident gadfly’s many accounts.  

With all joking aside, I’m confident that from the listening position, a half dozen strategically placed throw pillows can influence sound more than any speaker wire, no matter how much it costs or which direction the arrows are pointing.

It also depends on the resolution of the system. If you have a system that is "more than neutral", it would be easier to hear the difference. When I say "more than neutral", I mean the system sounds brighter than usual.

For example, if you intentionally have the tweeter level more than a few db above the rest of the audio frequency, then any changes in equipment can easily be heard.

And of course having a good hearing also helps.

Obviously. People with “state of the art” speaker wire from Parts Express: obviously they don’t have arrows. Therefore… wires are not directional. Very obvious. Case closed. Abort abort abort the pursuit
