Sample 1 sounds smoother overall and a bit more open to me.
Sample 2 has a bit of a silibant peak in the treble.
I eq'd both to taste on slightly dark Senn HD650s and dialed in a slight high end shelving boost for 1 and the same with a notch in it to cut the silibance for 2. Less of a difference on the low end, though I made a slightly different and smaller adjustment difference which I cant remember now (last night, late). Both sounded good, but forced to chose, I prefer 1.
Thanks for the listen.
