I agree, its hard to imagine this would make a significan difference, but I firmly believe everyone's system has strengths and weaknesses and improvemnts for some might not be for others and vice-versa.
That being said, as a former VPI Aries 3 and SDS owner, maybe the SDS 'acts' like an amp. Minimize the vibrational aspects to the cabinet of the SDS and it could conceivably improve it's ability at volatge control and thus speed control to the motor. Better speed control equals better sound.
What would be interesting is if someone would us the Feikert iphone speed app or another measuring device and measure the speed accuracy of the SDS with and without the terrastones. That would definitely confirm what Stringreen could be hearing.
