RE: Apples and oranges

I agree that the perfect sine wave is not always coming in through the wall. But the distortion is relatively small.

The question would be how much that slightly misshaped sine wave actually contributes to any sound when it runs through a rubber o-ring / belt to the heavy platter. And consider that with the motor running at about half voltage (60v from the Variac), the "noise" would be reduced by that much into the belt because the torque would be less with the lower voltage.
