The Physics of Electricity


Can anyone explain clearly in either common parlance or technical terms the difference between a $1,000.00 cable and/or speaker wire versus a $20.00 (or so) one? What does wire "do" in an expensive cable/wire that an inexpensive cable/wire does not? Does it conduct more or "better" electricity?

It's like a Toyota vs a Ferrari.  They will do grocery shopping just fine, but how you get you there is the difference.
Gentlemen, note that this is an eight year old thread, that was resurrected earlier today by a newly registered member. Judging by his post, his sole purpose in doing so was to publicize a particular course, most likely for SEO (search engine optimization) purposes (i.e., to elevate the position of the site he linked to in search engine results).

" more or better electricity "  = NO

As one person brought up
This debate has been going on since Monster cable was introduced ,
which I started using because they DID make a difference and in those days it was an inexpensive improvement .

There has been several responses that try to explain why
but there is not 1 why or because , 
each manufacture will sound different in different systems .
If there was 1 answer then all cable makers would be doing the same thing , using the same materials  .

While I have experienced moving up thru one manufactures lineup offerings my next move UP might be making my own speaker cables
using the same maufactures bulk cable ( 9.5 awg ) using anothers 
spade connectors for less than 1/5 of the list cost of a compairable gauge preassembled cable .

I guess one can have cake and eat it to !





@williewonka  These PS Audio articles are good primer except for possible errors like this:
The electromagnetic field is strongest nearest the wire, decreasing with the square of the distance moving out away from the wire.
It is not the square of the distance but just distance (linear fashion).

Magnetic field of wire carrying current  B = I x u0 / (2 x pi x r)
where I is magnitude of the current in the wire and u0 is permeability of free space.  Inverse square law applies to single point magnetic field and not to long wire carrying current.
