Interconnect Inductance vs. Capacitance


How do the inductance and capacitance of ICs impact the sound? I have seen some ICs that have low inductance but high capacitance. On the other hand, some ICs have high inductance but low capacitance. One manufacturer even claims that his higher models have higher capacitance.

So can someone explain to me how they impact the sound?

High capacitance can be a tough load for consumer grade gear - best to stick to short runs or low capacitance IC's. You can lose dynamics and in some extreme cases you get distortion.
Assuming you are referring to analog ic's carrying audio frequencies (as opposed to ic's carrying digital signals or other high frequency signals such as video), inductance is likely to be insignificant.

High capacitance may cause the highs to be rolled off, particularly if the component driving the cable has a high output impedance. That is because the output impedance of the driving component and the capacitance of the cable form a low pass filter, having a bandwidth corresponding to the product of the output impedance and the capacitance.

It is true that some very high-end cables have highish capacitance. That is one example of how some high-end cables are designed to be non-neutral. It is also an example of how cable performance can be system-dependent, because the effects of the capacitance will be dependent on component output impedance.
