Damping Plates

Lots of discussions about isolators and couplers used on the bottom of components but not much said about dealing with internal resonances using damping plates on top of the equipment. Harmonic Resolution Systems (HRS) is one of many manufacturers that make such devices but, like all things with an audiophile label, they can get expensive. Low-cost alternatives such as scuba dive weights have been mentioned by some.

Have you tried damping plates and were there worthwhile improvements in sound quality?

I use them on all my tube components. I have various footers, mostly DH Cones with maple platforms to drain component and rack vibration.
I'm using Edensound damping weights on top to prevent acoustic vibration; 
two damping weights evenly placed on top.

On equipment with contiguous top plates (no exposed tubes)  I spray painted 2.5 and 5 lb. bar bell weights and glued a thin cork sheet under.

@mesch , great minds think alike. I needed to damp a new  component but didn't want to spend any more money so I used 2.5 lb. weights and added a cork bottom.

@mesch , I have the cork on the bottom. They stay in place just fine with no scratches. 
I didn't want to use rubber, even synthetic, in case of residue. But @david_ten can speak to that.

@noromance , dont know. But maybe not a good idea to have bare metal touching the amp.
My weights are lined with cork and are on top of sources.
