You might experiment with lowering the shunt resistance across the
cartridge.  Shortening the cable from the cartridge to the preamp might
help by moving a resonance out of the audio range.

A "high end" friend of mine thinks the some of the Grado cartridges are
great, but the one he played for me was tinny for my taste.

A quick emprircal check of the tonearm is to hold the cartridge up with
a length of thread, and gently move the thread back and forth.  If the
arm follows easily without any obvious friction, and if it is properly
adjusted for geometry and force, it is unlikely to have any gross effects
on the sound.

If you are still playing records these days, I suggest you get the best
Shure you can afford.  The Shure V5 series seems to have the best
tracking, which along with the dust brush should give the longest life
for your recordings.  The V5 is also less sensitive to preamp loading
than some other cartridges.

But, you should realize that records are often overrecorded on sibilants.
The low distortion of CDs shine in vocal recordings, especially opera.
