I never really thought of it as "double grounding" but both the TT and tonearm ground wires are grounded to the phono preamp on my current Victor TT-81/UA-7082, as they were on the Technics SP-15/Rega 250 setup that preceded it. Never tried it with only one ground attached, so can't really comment on the difference. Both were dead silent in regards to static noise.
