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?

Just an additional thing to think about, my sister is a Neuro Researcher who spends a considerable amount of time listening to neurons fire in the brain. The cables she uses were over 100,000, are submerged in liquid nitrogen, and are absolutely directional. 
The cables she uses are heavily shielded due to the extreme, extreme low signal levels, and that is why they are shielded, not because the underlying physical cable is directional.

Are you saying the cables are submerged in liquid nitrogen in use?
That’s it. PF messed with the directions of their cables. Probably why I don’t regard their recordings as reference material.
