This can indeed be a problem: trying to produce a 'stabilised' power-supply for an audio amplifier or a RF/SSB linear-amp that has to follow current-demand at an audio-syllabic rate can easily turn into an exercise in designing what amounts to another audio-amplifier!
Slew-rates, settle-times and loop-damping...
