Directional?

There are plenty of other threads that cover this subject. Please start reading --don't start the subject up again for the literal hundredth time.

thanks.

The only reasonable answer to this is shielding should be connected only at the source. Not all audio cables are shielded, and chances are good even this makes only a tiny difference. 

What Audioquest(et al) think(s): https://www.audioquest.com/theory-education/article/83-directionality-its-all-about-noise Possibly part of the reason OCC(Ohno Constant Crystal) wire is so popular, in the industry's better cabling.

Your transparent plastic covered from the local shop selling 10 - 14awg OFC copper speaker cable isn't directional. Only shielded cable terminated at on end (and marked by arrows or some such) may be directional. You need to look at the cable. Some do some don't, some are, some are not. Does it make a difference? I don't know because I haven't been able to afford such cable.
