Dave -
I'm going to have disagree with you on this as there are in fact some digital eq designs that take advantage of having less steep anti-aliasing filters during processing after upsampling to provide better sounding results - especially when equalizing higher frequencies - as this allows there to be less "pre-warping" where the filter's shape loses it's symmetry as the frequencies head towards the Nyquist frequency - more info at

Here's a pic of a filter with and without the effects of "pre-warping"
