spacial-temporal resolution of the human ear is, as a pair, and to some extent individually: exceeds a requirement for a jitter free 200khz/20 bit reproduction in digitally based signals....
the amplifier tends to be the same. the seeming contradiction is a excellent sounding tube amplifier that may only go out flat to 17khz or the like.
the situation is complex, at best. clean non phase-shifted bandwidth and similarly important clean dynamics is helpful, regarding both being a specification involving an amplifier.
Yet... a tube amplifier can violate both to some degree and still sound good...
