Default Huge rail caps needed w/reg SMPS?

Are large electrolytic capacitors needed in the supply rails of audio amps when powered by a regulated or even unregulated switchmode power supply? I understand the need when running off 60hz xfmr and rectifier because of the long time between cap charging, but it seems the caps could be much smaller when recharged every few microseconds(or less).
