Come on Tony that's a bit disingenuous.  You won't find a single avionics engineer who would give credence to cable directionality and general "wanky wire" concepts that are bandied around in the hifi world.

Avionics, and all other branches of critical electrical/electronic engineering follows strict scientific principles - not hokus-pokus theories.  Sure, minimizing interference is important but that's got nothing to do with cable directionality, it works on sound scientific principles.

I don't think it's entirely fair to use the fact that your parent company works on aerospace products to add credibility to your audio cables from a scientific standpoint.
