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

yes its a definite improvement, a preamp with tubes benefits more than a digital converter.
