Having thought some about this. Do you mean in AD-converters or 
in DSP? I don't know too much about state of the art AD-circuits, 
but I would imagine that they use a higher internal sample rate 
so that they can use an analog filter that does not affect the 
audible signal in a destructive way, followed by a digital 
correction filter followed by decimating? The result ought to be 
neutral?

Or are you talking about side-effects from low pass filters in 
the DSP process, moving the knee (-3dB) of the filter out of the 
audible range by using oversampling? But regardless, you should 
be able to use a phase-correcting allpass filter, if desired…?

I am not trying to be difficult, but I am trying to understand 
the context.
