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?

if I were PS Audio I wouldn’t have posted the error-fraught Belden engineer article on his website. Maybe he didn’t know any better. Maybe he assumed it was accurate since it was an engineer from a wire company and was trying to give credibility to his web site. Who knows? Maybe he was letting the Belden engineer speak for him. That’s the perception.
Geoff - One error is hardly "Error-Fraught" 

Except for that ONE error -  the other points covered are valid considerations when designing a cable don't you think?.

Steve, you must have missed my post. There are many errors in the first article. My original post was,

Geoffkait: “Whoa! Somebody flunked electricity big time!. The audio signal is not the music waveform and electrons don’t travel through the cable. And magnetism is produced by current moving through wire, not by electrons. The B field is the induced magnetic field. Hel-loo!”

Gosh, Lizzie, I thought you argued about anything. You must be slipping.
