Sounds to me like the cartridge's suspension is faulty.I had a very
similar experience with my AT-F5 moving coil when it got very old.It
played ok but between tracks you could hear slight tinkling noise.Also
just check that your tracking force is not too high and that the
cartridge is not grounding on the LP.

Depending on what's really going on here, that does not sound good!
Is the "rattle" mechanical sounding as if it were coming from the
point where the cantilever enters cartridge body? OR is it a sound
coming out of your speakers? I'd suspect perhaps both, since we're
dealing with such high level amplification.
Is the tonearm secured properly? My experience dealing with modern
turntables is that when you purchase something that has been setup
"at the factory", there is almost ALWAYS something wrong with the
installation of the cartridge, stylus (if removable) and the tonearm.
Check to be sure the tonearm is not about to fall off. And twist the
tonearm as if you were adjusting azimuth to ensure it is "locked" in
place.
Looking at this turntable, I see the headshell comes off on this model.
Make sure that is fully seated and that the screw holding it on is
turned all the way in. If everything seems A-OK, any chance the cartridge
sitting in the headshell is loose? I wouldn't think so, but...
Oh, and assuming the downforce is properly set, perhaps you have a
funky spindle, bearing or platter problem? If you hear this rattle
through both the speakers and TT, maybe the sound is a result of a
bad drive system? Wouldn't surprise me at all with the way these
transit companies (ESPECIALLY UPS) handle packages these days ;-)
Be certain the cart mounting screws are secure
and you have the counterbalance properly zero'd before
setting the tracking force.
A stylus force gauge may be in order..they can be inexpensive.
Increasing the setting and see what happens won't hurt.
I prefer to run a little on the high end of the recommended range
feeling the mistracking is far more damaging to vinyl than a little
extra force.
I'd also suggest that perhaps the cart is a poor match for the
arm but since it was a package by A-T, that should not be the
case. Still a test track to show cart/arm resonance might
be useful.

I think I'd check the tracking angle too. A cartridge that's mounted so that
the stylus plane allows the cantilever portion behind the stylus to touch the
record or the cartridge body itself is allowed to touch the record, it can
cause noise.
I think the OP must have taken a good hard look at the
stylus/cartridge/tonearm combo making certain all remains clear of the LP
surface. Could it of happened that the stylus assembly became loosened when
a stylus guard was removed? I suggest pulling the stylus assembly out of the
cartridge body and then pushing it back in firmly as far as possible into
the cartridge body. (I suppose it's a P-mount cartridge so loosened
wires/lugs are out of the question.)
So, all you've been talking about is the normal up-and-down motion
of the tonearm/cart assembly, as it rides the not-perfectly-flat surface
of the LP?

You always need to route the signal through a phono preamp, so I
suggest not using anything other than Phono.
If you do buy new gear, makes sure the receiver (these days it's likely
to be an A/V receiver or 'AVR') has a Phono input.
