Hi Rmml - ya I used 3 zip lock freezer bags sealed with electrical tape and separated from the preamp by a gasket inside of each dome to contain the sand... I might re-think that tweak too.
Since I've had the sand filled domes for a while, I plan to remove them soon (maybe today) and test without the sand to see if it really makes as much of a difference as I originally thought. I'll let you know.
