MDF Rack dampening question

Hello all,
I'm using a 4 shelf MDF rack that has hollow alum metal columns, and plastic looking (may be silicone) footers. Floor is porcelain tile. There's lots of empty space between the shelves.

I feel vibration on my equipment while listening to music and I'm wondering if there is anything I can do to help eliminate this (short of replacing the rack)

Some ideas I am kicking around are listed, wondering if you have tried and if it made any difference.

Fill hollow metal columns with sand
Changing footers to brass spikes
Dampening material under each shelf (Dynamat Extreme or another) which would also block EMF between shelves
Mounting each piece of equipment on butcher block w vibrapods (or similar)

Regards,

I would start with filling the tubes with lead shot. Then if you add spikes make sure you use cone rest between spike and floor. I think butcher block would be a waste.
How thick are MDF shelves and are you sure they are MDF and not particle board? MDF really should deaden vibration which is why speaker manufactures love the stuff.
I think these measures would be a good start and possibly the solution.
