Weights on top of equipment to dampen vibration

I use coated solid scuba weight belt weights. Completely dead with no resonance.

A scrap of Corian countertop or marble works well on unvented gear. I use a slab of corian on top of my
CDP.

I use the KISS theory
Normal 15lb dumbells on top of each transformer ..works for me

interesting Tvad Where did you get the brass weights from ?

Important to note the weight doesn't sit directly on top of the transformer I have a blue circle puc in between the two surfaces

I checked Palmetto audio for the carbon blocks it doesn't look like they carrry these any longer.
