The SME suspension towers are heavily damped, so pushing down on the plinth does not get it to oscillate. Likewise, the Vibraplane is fed by a compressor, so as soon as one corner is pushed down, the air bladders immediately fill up and so it does not oscillate either.
I have not tried to defeat the suspension of the SME and listened to it on the Vibraplane. I only compared the table with and without the Vibraplane, and it is better with the Vibraplane inflated. The motor controller isolated on the Vibraplane also makes quite a difference.
Thanks for your suggestions. BTW, I thought that if they are 180 degrees out of phase, they would cancel, and it is only when they are in phase that the cycles amplify to cause problems.
I suspect all is fine, because I have never seen either move and the sound has never been better. But I wonder if the isolation is redundant. I'm going to try to defeat the isolation on my the SME towers this weekend and give it a listen.
