Evidently, I didn't express myself clearly, but let me try again.
The springs don't go directly beneath the turntable cage but rather below whatever platform the tt sits on, in my case a sandbox. The weight of the tt + platform results in the spring having a certain frequency at which it moves. My sandbox and tt weighed around 150 lbs and there was certainly no bounciness to the system. I take it no one believes one can turn a non-suspended table to a suspended one by changing the type of platform the tt rests on. Or am I missing something?
At any rate, Halcro, you mentioned an issue with low frequencies affecting the tt-101 and I thought this might be worth a shot, since it theoretically at least allows one control over just that.
But if one is like Gary and you "don't have any issues that require amelioration" then I'm truly envious :).
