What kind of amplifier needs big caps to drive bass?

[Joe Bloggs]

Does this only apply to amplifiers that do not have enough current ability to drive DC through a headphone's impedance load (not actual headphones of course as DC would damage them) for an unlimited amount of time? Are there any headphone amps that don't need caps to drive bass? What about speaker amps?

Joe: I guess, you are referring to big elcaps in power supplies, are you? Well, these are good for any amp, actually: You need the elcaps for smoothing the output voltage of the power supply and as electron buffers, that can deliver their stored energy quickly when needed. Some designers like Michael Creek use several smaller elcaps parallely instead of bigger ones, because that further reduces the inner resistance of the power supply - in order to make the amp faster and more dynamic.
