I know we have some engineers here. I wish we had a materials science person also. I clearly get the basics. Ohm’s law has not been repealed.
What wonders me some (I live near Amish country), are these factors:
-
We’re talking about a 2M long cable here, not a long stretch
-
We are also talking about audio frequencies - how much can things like skin effect, and impurities or crystal structure of the wire matter. Capacitance yes. That can be measured.
-
Dielectric material. In a 2M long cable, how much of an effect can it have?
-
I don’t get the litz cable discussions. If tiny strands are coated with insulating material (aka dieletric material) how come none of the discussion seems concerned with dielectric effect in that cable? What about capacitance? What about termination, or does solder or crimping magically take the coating off?
I can see some of the arguments when talking about long runs of wire, especially when you are running wires through walls. But 2M? I would like to hear results from double-blind tests.
