Trebejo, Jim Thiel had a degree in physics, and though I can't say for sure that he actually spent money on magic cables, he did have some prefered cables that he would diplomatically recommend for use with his speakers.
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?
