(I am ashamed to admit this but) I have an old pair of Monster 1/8" -> RCA cables and they are directional. I was confused by this and looked up this on their website. It says:
Why do the cables have directional arrows?
This is done for shielding purposes only, a design where we do not solder the shield on the signal's destination. This ensures that any noise picked up by the shield will not be transmitted into your signal path.
Can I assume that any other cable that I buy will not be directional? For example, I want to get the Blue Jeans Cable RCA-1/8" cable or similar and want to use it from my DAC or GS-1 line out to the Pico Slim.
Also, I don't understand Monster's explanation. Why would this make it directional?
