Interconnect Directionality


Have I lost my mind? I swear that I am hearing differences in the direction I hook up my interconnect cables between my preamp and power amp. These are custom built solid core silver cables with Eichmann bullet plugs. There is no shield so this is not a case where one end of the cable’s shield is grounded and the other isn’t. 

There are four ways ways to hook them up:
Right: Forward. Left: Forward. 
Right: Backward. Left: Backward
Right: Forward. Left: Backward
Right: Backward. Left: Forward. 

There is no difference in construction between forward and backward, but here are my observations:

When they are hooked up forward/backward there appears to be more airy-ness and what appears to be a slight phase difference. When hooked up forward/forward or backward/backward, the image seems more precise like they are more in phase. The difference between forward/forward and backward/backward is that one seems to push the soundstage back a little bit while the other brings it towards you more. 

What could possibly cause this? Does it have something to do with the way the wire is constructed and how the grains are made while drawn through a die? Am I imagining this? Have I completely lost my mind?

The cause for differences in sound are more due to placement / routing of cables than anything else. This is because the OP’s cables are unbalanced and unshielded, therefore very vulnerable to interference. Bottom line is, if you insist on using unshielded cables, make sure they are twisted pair, and preferably balanced with as high a source signal level as the receiving end will tolerate without overload. 
The flow of electrons for an audio signal is in both directions Geoff, from one terminal of the source to the other on the positive half cycle, then in the opposite direction for the negative half cycle. If you could optimize electron flow, favoring the positive half cycle over the negative half cycle, (or vice-versa), you would be distorting the signal. It’s never too late to wake up from the dream of “cable directionality“, and embrace reality. 
Geoffy, wake up, (rpt, wake up). Get on the reality train 🚂. Photon movement in opaque substances are as fictitious a concept as Donald Trump telling the truth. Free electrons from the outer shell that move from atom to atom make up the flow of electrical current. In alternating currents, this flow is in both directions, depending on the instantaneous polarity of applied potential difference. 
Geoffy, you still have not made a case for why directionality exists, much less of how it’s implied asymmetry of energy delivery could possibly be a benefit to sound quality.
