I think we are now listening to differences in digital filters more than any other differences in our digital playback systems.

Your thoughts have crossed my mind too. A friend of mine always listens to native format and insists it sounds more detailed. If you look at the math up-sampling should increase detail (resolution) by plotting extra data between native sample points. Indeed we may be hearing artifacts from digital filtering or/and the process of up-sampling may be doing things Science does not fully understand yet.
