Thanks for clarifying that.
It is a problem when you are taught the analogy of plumbing where; water flows through pipes, just as electricity flows through wires , if they are made of copper, in this case. (That was a nice touch in the Cal Tech experiment.) It completely screws up the individuals understanding when learning about electronics in depth, and there have been tons of posts here where knowledge of the true nature of electric current flow would benefit the people posting them and help them understand other posts as well.
That brings up my point. The fields that exist in a stereo system are many, and they do interact with one and other at many different points in the system, think components stacked on one and other, very bad to have the power amp directly on top of the preamp; big transformer, big powerful field. But this would reinforce peoples arguments that separates sound better than integrated, would it not?
But, as Amir points out on his board and YT videos, most of these fields are negligible from a performance and auditory standpoint. Simply beyond the range of human hearing. Probably a good idea to have more MuMetal on the inside of every electric component though, especially an integrated amp.
My question is this: Does this explain why twisting speaker cable seems to be the first rule of improving speaker wire performance? (Oddly enough, sort of like DNA strands.) In other words; if you took those cables that go off into outer space and return and twist them, still maintaining the distance between the two, does that intensify the field between the two parallel wires and help isolate them from outside field interference?
Thanks for all the hard work and sharing it.
