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.

Objective laboratory analysis of different cable materials and not existing commercial cables would be an appropriate starting point. Defining constants, testing and publishing the results would generate an empirical baseline. The additional analysis of configuration, cover material and conductor mix would be invaluable when selecting a cable "family" for listening evaluations. The audio market place is ridden with tweaks and methods that each developer feels enhances the aural product. Some product developers will use confirmatiom bias to capriciously select isolated test values that "confirm" their beliefs and bolster their claims. The determinants for product purchase will continue to be inviolate...did I spend as much or as little as possible (bragging rights), is the appearance right (looks great on and off) or is the sound what I want (subjective perogative)? I will personally buy or make new IC's and speaker cables in the next 2 months. The search continues for a flat response, broad bandwidth wire and connector combo that doesn't require robbing a bank.

What is the resonant frequency of earwax?
I'm going to connect my turntable to my cochlear imlants and skip the rest of the system.

I posted that question hoping to draw some of the snipers in the thread. In reality the acoustic characteristics of the canal vary widely and the artifacts of residual cerumen do alter the mechanical feed to the tympanic membranes. The membrane and 3 bones(incus,stapes and malleus) send the vibrations to the hair cells of the cochlea. At this point the mechanical energy is converted to electrical impulses that the cochlear nerve supplies to the brain(Broca's area).
What arrives at the brain is influenced at each of these junctures. Do clean ears optimize sound... I think yes! Should your audio system be tuned to compensate for inconsistencies in tympanic output(confirmed by audiogram)...I don't know. Would any of this standardize the listening experience? Tweaks for rooms, cables, electronics and speakers are de riguer. Should we tweak the organic end of the system as well?
Next week, sound modeling in the middle and inner ear and do the Eustachian Tubes control porting in your head.
