I have a quibble here:

In the cases I have worked with, the capacitors actually have much better
response to dynamic load swings than the rectifier-transformer-60Hz line
behind them. The problem is that they can only store so much energy, so
eventually they can no longer cover up the shortcomings of these other
components.
