If anything, the frequency response for digital equipment could be more
limited on the upper end than that for analogue equipment, some components
of which boast response up to and beyond 40 kHz whereas current home digital
equipment cannot offer any signal higher than 22 kHz.  Whether that makes
and audible difference, all I can say is "God only knows" - the fact that
I may not hear or perceive it doesn't say that someone else also can't.

Generally "digital ready" refers to the equipment's capacity for the
increased dynamic range supplied by digital recordings and playback
equipment.  This would refer to the power handling capacity of the speakers
and the amplifier's ability to supply sufficient power for loud passages
without clipping.

Another meaning I've seen given to "digital ready" in advertisements for
preamps (whether alone, or as part of an integrated amp or receiver) is
the inclusion of a high level ("aux") input whose sensitivity is reduced
so as to avoid the overload problems that can arise when feeding the
outputs from some CD players into the standard high level inputs of
some preamps.  Of course, this is unnecessary if the CD player has a
line output level control, as the Magnavox 3040, for example, does.
