I've also now tried several sets with different numbers of harmonics.  I found I could detect a
*tiny* difference when I got past 8 sinewaves.  I think that this could very likely be due to
speaker dynamics as well as sound card problems.  Unfortunately, I think we are suffering from
several factors over which we have little to no control.

Another thing that just occurred to me is that higher harmonics are represented by fewer samples
and as such, I believe their approximation will be less accurate.  So as we add more and more
sinewaves that are less and less accurate, this effect seems to stand to reason.
