Guiddog - I've tried some of the hardwood materials suggested above and also granite and MDF.
The problem I found with all of them is they all tend to vibrate at some point in time if they are not "treated".
One solution is to construct each shelf as a "sandwich" - i.e. between two layers of shelving material place a layer of the foam rubber material used to line drawers - the stuff with all the holes.
The sandwich significantly reduces vibrations in both layers.
Another approach that is easier to implement, is to get a sheet of sorbothane and apply it to the underside of the shelf. Provided the underside of the shelf is smoothly finished in some manner (like urethane) as the sorbothane naturally adheres by vacuum, so it can easily be removed without leaving any residue.
You can easily experiment with the alignments i.e. either the square sheet aligns with the front/sides/back of the shelf or at an angle might be more beneficial.
Re-applying a sheet may cause it to lose it's tackiness, so simply wash with plain water under the tap, or better still wipe with isopropyl alcohol to restore it.
Either of these treatments will significantly reduce the vibrations in any shelf.
A 1/10" thick sheet of sorbothane sheet is all that is required - Thicker may not improve it's effectiveness - but will cost you more
Sorbothane sheets are available from Amazon/Ebay for around $25 for one square foot and is widely used by the HVAC industry on furnaces, plenum's etc. to curb noisy installations
Good luck with the stand :-)
