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


Here is a very relevant discussion among physicists about the directionality...the way signal and electrons should flow... based on conductor orientation. Some esoteric, high-end manufacturers say they listen to each conductor to see which way the signal should flow for the best audio quality.

Read this discussion. Will it make you rethink what you’re being told and sold?

I like: Silversmith, Inakustik, Black Cat and for value Analysis Plus. What I have heard from Purist was also extremely good. The best small company cable I have heard is Bionics Cable which may have to be made to order.

Yup, a conductive alloy that is liquid at room temperature....and has been used to very good effect in audio cables for over a decade.

The three levels of entry level cables are not that pricey given the performance they deliver ( the entry you posted btw is quite old and we have since extensively revamped the line-up to include some more cost friendly products ).....and as for the HAZMAT issue, it does apply to one of the elements found in the alloy, but not the alloy itself which is very stable ( the problem with gallium is it melts aluminum and since the HAZMAT folks are closely tied to the airline industry anything that could potentially compromise an air-frame at altitude is a big problem, therefore the HAZMAT issue ) ...as for the implied negative interactions of the alloy with clients, not a problem, in fact the alloy has been used in medical grade thermometers as a safe alternative to mercury for a couple of decades now ).
