MDF sand box tweak - effective for DAC, pre-amp?


Hi all,
I have heard about the MDF sand box tweak (a MDF box that
contains sand - the lid of the box rests completely on sand)
under CD player or turnable with good results.

Has anyone implemented this tweak under DAC or pre-amp?
How effective is it?
I appreciate your feed-backs

Buckingham had the same idea as I as I was reading this thread, except I would use Corian for the entire thing. They have pre-cut back splash material which would make the frame, then use sink cuts for top and bottom. Just remember to leave a gap around the lid. I live in Florida, so I'm pretty familiar with sand. Can someone fill me in on how wood of any density would be better than marble or Corian? I thought the whole idea of these was to eliminate resonance? Thanks
