Directionality of wire

nonoise...

Sure, but as I alluded to, its not in the audio (more specifically analog vs digital) world. I wasn't trying to take subject matter beyond the interest in audio.  However in the RF (now we are out realm of "wired" interests) world, where one is interested in "using" low power RF signals emitted in free-space, there are numerous instances where directionality is impacted by material construction (type of insulation; Teflon being but one good example), type of conductor (Silver plated copper, and in some instances pure silver-  silver is a better conductor than copper), terminations, etc. and all are considered to reduce transmission losses (insertion losses), and maintain gain when you have exploited all that's possible from things like antenna gain, pattern coverage, etc.  However, one is dealing with signals that are much lower in emitted power than normally seen in low-power level signals from your phono player, CD, Preamp, etc. Often one is also dealing with frequencies that are in the GHz bands, not KHz as with audio.  However, none of this is fair nor applicable to the subject at hand.  Frankly the benefits of such wiring just isn't cost effective with audio signals.  However, that doesn't mean its not used to help sell lots of signal IC and speaker cables.

However, I'm sure that geoffkait can well appreciate some of this since he is totally wireless anyway.  I'm still working on my wireless approach, but alas its limited to Blue Tooth and WiFi as well as 2.4 & 5.6 GHz home networking products.  I'm still researching Nickola Tesla's work in wireless power transmission to see if I can build my own Wardenclyffe Tower, but my homeowners covenants prevent having one as tall as Tesla had.

Of course it was Marconi who had the first long distance radio transmission after much ado. In fact, it wasn’t until many years after he first embarked on his long range radio transmission mission that he realized he and just about everyone else had radio signals figured out all wrong. He was building taller and taller structures and pumping more and more power into the transmitters trying to achieve more and more distance, but misfiring and producing a few castastrophies along the way. Much to his chagrin, Marconi miscalculated that the wavelenths for long distance transmission had to be very long, whereas it turned out they had to be very short. So it wasn’t high power, long waves that was needed, but low power, short waves. Shazam!

My, a true renaissance man if there ever was one- good show!

We have much to appreciate in the modern world due to the contributions of fellows like Marconi and Tesla.  Just think what it might be like w/o them.  DC power and a power generation station at every major corner & intersection...   

I forgot to add that we would indeed have directional wiring in any case if we had DC for primary power.
