From the XMPLAY.TXT file...
Interpolation switch - MOD formats only
   "Linear" interpolation "draws" a straight line between the samples,
   "Sinc" interpolation "draws" a smooth curve between the samples and
   requires more CPU power.

So, basically, interpolation joins the dots :D

Yes, it improves quality, though some old MODs may sound better without it (as that's how they were created).
