I have never had any problem with any of the 3, SOTA suspended tables I've owned. I currently own a new NOVA.
I have locked down the springs on a Star Saphire I had owned and really did not notice a drop or improvement in sound quality.
A suspended shelf is a good idea in any case BUT NOTE that a standard 2x4-constructed wall vibrates to a greater or lesser degree depending upon it's location within the home. (Ever notice that some wall-hung pictures are always moving?)
The suspended shelf needs to be one of a higher quality that is designed for minimizing the effect of the table being cantilevered, especially if it is only being anchored to two wall studs and the table is a heavy one such as a SOTA with isolation spikes. Otherwise the weight of the table magnifies the wall vibrations and creates oscillation of the cantilerered shelf carrying the heavy turntable. In some cases this has the potential for creating vibration that will feed through the cart and perhaps annoy a more discerning audiophile.
Personally I don't see the need to introduce a shelf into one's system unless your floor is incredibly bouncy.
