Hello, I'm having the damnedest time wrapping my head around a concept of audio electronics:
http://whirlwindusa.com/support/tech-articles/high-and-low-impedance-signals/
How exactly does a higher impedance bring down the frequency at which capacitance dominates? My current understanding is that the frequency at which capacitance will dominate is dependent on the capacitance value. Through what mechanism of physics does the a increase in source or input impedance decrease the frequency at which capacitance dominates?
Thanks!

High impedance lines are more adversely affected by the inherent capacitance that is present in the cable itself. This capacitance combines with the impedances of the source and destination to set up a filter. As the impedance increases and/or the capacitance per foot increases, the active frequency at which the filter comes into play gets lower.
