wire speed

frequency and wire speed.

jUst read this in an article by Ultra Audio

A fellow named Heaviside established a clever way of making the various frequencies traveling in a wire go at the same speed by balancing the speed-increasing effects of capacitance with the speed-slowing effects of inductance. This is called Heaviside’s Condition. Cables in which the ratio of conductance to capacitance equals the ratio of resistance to inductance (G/C = R/L) satisfy Heaviside’s Condition and may sidestep this problem (assuming all the other sources of distortion are controlled).

This is what MIT and Transparent are doing in their boxs but a couple things confuse me.

First can a capacitor actually increase the speed? Don't think so. Second does and inductor actually slow speed?

If (G/C = R/L) where G, conductance = 1/R then L/C = RR transfer into the frequency domain and LCss = RR or s = R/sqrt(LC). Certainly L and C are fixed in passive components but in a wire R varies depending on frequency and current depth and density but how much. L also varies as frequency rise the wire starts to act as a wave guide and inductance is minimize don't know what happens with capacitance.

Any thoughts are welcome.

Cheers

My only thought is that somebody is sure to come out with some $$$$$$ cables that are supposed to take advantage of this to some tremendous sonic benefit but which actually sound the same as some 16AWG from radio shack.

At audio frequencies this would be negligible until a cable length of around 200m.

what would be?

is this article online?

Heaviside’s Condition, the topic of the thread.

Pay attention Heavyside is NOT the topic thread brainchild propagation velocity is.

Yes try a search for it under Ultra Audio if that doesn't work let me know and I can send it to you

Who cares Lopan? Neither one will affect your audio cables

unless you "think" it will!

so what's the point of name calling?

clearly this discussion is over your head with radio shack lamp cord speaker wire
