Sound of 910FD versus 913FD

Does 913FD sound nicer on contact than 910FD. I like the performance of 910FD very much but did not particularly like the sound.

I was surprised that the sound of 910FD was so different from 910F.

According to Titleist it does.  The 913 FD has higher level of acoustic engineering than that of the 910 series.  I for one loved the sound of my 910f so I look forward to seeing how this is.
