I'm embroiled in a discussion on aus.hifi with a poster who recommends

use of RG58C/U as speaker cable (with alleged sonic improvements over

Wouldn't the combined inductance/capacitance of this stuff constitute an
LC
filter causing signal attenuation or, worse, amp output stage
instability
over anything but a short run?
Patrick Turner? Anyone?

Most ppl manage to ignore Thevenim's Theorem that tells you all the
R's in a series circuit need to be added in to get the final answer.
The part left out in this case is usually the speaker R which in most
cases is by far the largest component in an amp output circuit. It is also
the reason why damping factors greater than say 5 don't do much.
Many will argue with the above. Better get out the text books!!1

And it's about time the WWF does something against the use of snake oil
