My transport sits on isopods, which are sitting on a piece of scrap granite... which is itself sitting on 2x2 rubber/cork/rubber squares... I also have a 2 gallon ziplock bag filled with a 50/50 mix of copper BB's & sand (they are triple bagged to prevent leaks). The bag weighs about 10 pounds altogether and spreads out perfectly over the surface of my transport. I have no jitter issues at all...
You seem to be suggesting that the mass loading combined with the footers on your transport is reducing vibration, which is probably true. However, the term jitter as it's used in audio to describe a phenomenon in digital playback, has nothing to do with mechanical vibration. Jitter is a term for electronic sampling errors.
