probably because the light metal (but still rigid) stand doesn't resonate at frequencies near the suspension resonance frequency. Also the higher frequencies are filtered out by the TT's suspension. BTW, airborne induced vibrations can act directly on the arm and cartridge (albeit slightly) and no amount of isolation, coupling nor massive loading of the TT can eliminate them, except distance, of course.
My turntable (Oracle Alex IV) is suspended from the ceiling on MDF board by four wires. Can't get a lighter "stand" than that!
