The most interesting thing is that Filter One is a non-phase-linear filter. Look at the ringing -- there is more on the left side of the square waves than the right side of the square waves.

This is more like the way an analog filter behaves. With an analog filter, *all* of the ringing will be on the left side (after the transition) and *none* will be on the right side (prior to the transition).

It's interesting the the consensus of the posters seems to be that Filter One sounds the best, because for decades everybody has been hyping digital filters as "inherently superior" because they are phase-linear. But at least in this case, apparently not.
