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

If you hear a difference but your measurement instruments are saying no difference, then there is something wrong with the way you measure. 

You don't go to your doctor to have your ears checked.  That would be a bit odd.  I don't know of anyone who would come to this conclusion.  

Years ago at CES I hear an active German speaker 4 way with early class D probably ICE modules that sounded much better than it should have and so much better I would guess than it would have if this design was passive. I also always favored the active ATC speakers and never liked their passive designs. These experiences have stayed with me many years later and have served as a model of the viability of active speakers. 

Might have been Geithain speakers.   Everything I've read about them they are incredible speakers, cartoid down into the bass. You don't hear much about them outside of Europe.  I believe they sell direct in the US but you get no support.

Yeah those active ATC ones are tres nice ain’t they.....really surprised how much better they were than their non-active kin, which until I heard the active ones thought they were pretty good...

If you hear a difference but your measurement instruments are saying no difference, then maybe you are measuring the wrong thing...
