As quartersawn is a different method of extracting a plank from a tree you get a greater number of grain lines and thus a denser wood which would suggest a difference in tone. Check out this link http://www.frudua.com/quarter_cut_vs_slab_cut.htm
Nonsense. That's physically impossible. Your own link shows how that can't be true.
The difference is in grain orientation, which can aid stability in some applications such as guitar necks. Past that, there's little to be gained by it, which is one of the reasons most mills don't bother with it. The other is yield, which nobody
but the mills care about. Plus, even with traditional sawing techniques, you end up with a percentage of the yield that's close to quartersawn anyway. Again, look at the illustration at the link you provided. A portion of the flatsawn lumber ends up essentially quartersawn. For those who care about such things, they can hand select flatsawn stock to get quartersawn grain orientation. One need only inspect the end grain to determine where in the log radius the cut took place.
Sound-wise, as it applies to guitar/bass necks, I sincerely doubt there's a lick of difference between the two. Although, If I was a bass player, I'd want the quartersawn orientation simply because the neck is longer and more likely to shift over time, causing problems with fret integrity. Get a twist or warp in the thing, and there's a repair expense that's often unbearable relative to total replacement. A quartersawn part is less likely to move.
