RE: Your thoughts please.

Just what exactly do you want our thoughts on?

How does an AC signal get from the source to the load through wires?
How does an AC signal get from the source (preamp) to the load (power amp)?


Quote. (Audiogon Herman)
In audio we are talking about the transfer of energy in the form of an electromagnetic wave.

Electrons and wires are not needed to transfer this energy. For example, the waves will radiate in free space or down a waveguide.

Current is the flow of charge, not electrons; however it is not needed to transfer the energy therefore the current (flow of charge) in the wire is an effect, not a cause.

At low frequencies like audio it is easier to construct a system where the energy follows a wire more easily than through space or a waveguide because the wavelength is so long and the waveguide or antenna would need to be humongous.

The water flow analogy is fatally flawed, it cannot explain everything that is happening with AC or DC. http://en.wikipedia.org/wiki/Hydraulic_analogy

Current flow is a misnomer with AC and causes great confusion since the charges are not really flowing. The periodic motion of the charge is not a flow in the conventional sense of the word. This is the only use of the word flow I have ever seen that describes periodic motion. For instance, pendulums do not flow. This basic misconception was the cause of much of the Audiogon debacle. Somebody was insisting that electrons vibrating about a fixed point could be described as current flow.
End quote.

Thoughts?
