HowdyA proper reconstruction filter has softened them just the right amount, i.e. back to their original (band limited because of the A/D's antialiasing filter) shape. Any further softening is some form of low pass filtering which is needlessly throwing away freq response.
Don't get me wrong, more resolution is good, but we're stuck with Redbook's resolution for CDs. Also upsampling isn't necessarily evil, it can allow a better implementation of the proper reconstruction filter, but this isn't a softening of the non-upsampled filter implementation.
