When you ground the tonearm, you create capacitance between the arm wire and the arm tube. The difference should be small, but might be measurable with a MM cartridge. With a MC cart, it should make no difference at all.

The only other things I can think of:

Is the increased hum changing your perception of the music?

Is there a possibility of some other grounding issue where the TT is closing a loop? When the table is disconnected there should be no contact between TT ground and any of the cartridge leads or earth ground.

EDIT:
One other suggestion, try connecting your ground wire through a resistor (100-5K ohms). There may be a value which eliminates hum, and isolates the TT from the preamp a bit.
