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

I use one under my TT VPI Jr and it is great. I also used them under my tube amps. Again with positive results. Little tweaks all add up to great results. I had a master cabinet maker make mine for $40 each. I painted them myself and they look and perform as well or better than the mass produced.
