Do materials alter frequencies and speed?

Thank you, The various cable combos use silver & copper, silver & carbon and copper & carbon. If each conductor brings its own transmission signature would the broadest spectrum be derived from the use of all three? I am mainly thinking about speaker wires.

This obviously impacts dynamics.

It seems the 'speed' of the cable is usually stated between 60-90% the speed of light, depending on dielectric constant od the insulator used. How does this affect dynamics? I thought dynamic range is based on the noise floor...

>>the higher the inductance and capacitance, the slower the signal will travel through the cable. This obviously impacts dynamics.<<

This is too general to be useful and also quite a leap.

How are you measuring dynamics?

At what point does an increase in inductance and capacitance cause an audible impact on dynamics?

What is the evidence for the audibility of this impact?

Are we talking about anecdotal testimonial or something more solid?

Sliver is slightly less resistive than copper, but you can overcome that by using a thicker gauge of copper.

Rsbeck -- "dynamics" are energy related. Lossy energy transfer can impact.
Frequency response measurement is time-related.
As to the evidence etc & alia, I believe Aball answered your questions, above. Cheers
