You can use DeltaWave to listen to the difference.
First, run the match between the two files. You can see some numerical results, but you can also press the play button next to the reference, comparison, or the delta files to play. When you press the delta play, you will hear the difference between the two files. When I do it with your files, I can't hear anything at normal listening levels. When I raise the gain control by 50dB, I can hear just a hiss -- no real sound, no music. This indicates that the difference between the files is just noise that's completely inaudible at normal listening levels.
As to how to interpret the numeric results:
1. The spectrum of the delta files shows that the difference is almost completely below the 16 bit result (which is why it sounds like hiss)
2. The RMS difference of -73dB shows a pretty good match, as does the 70dB correlated null value
3. There is a very small clock drift of 0.04ppm -- this may just be due to noise, as this value is very low.
4. Only about 3% of the actual samples between the two files match, so they are not bit-perfect
Phase differences indicate no real differences between the two:
If you look at delta spectrogram, you'll see very little difference between the two except for noise, also.
