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?

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. 

The brass damping weight mentioned by lowrider look nice and come with cork or some type elastomer base. For equipment with exposed tubes I would want a base that keeps these weights from slipping.

@ Yes, I looked that up. Which have you used, cork or elastomer?

@david_ten  In your opinion does the elastomer prevent slippage to an extent greater than cork?

To better understand my interest, I wish to use these damping devices as much to add mass to the UV-1 as for the damping per se'. It is very light and presents a need to counterbalance cabling. Thought I do have my cabling routed in such a way not to add too much strain.

@lowrider57 which base type do use on your Edensound brass damping discs. I would want to keep than from sliding on surface of any component with exposed tubes.

@lowrider57. Thanks. Just to let you know, I have a UV-1 on the way. Looking to use the damping as you did with yours. I thought that the brass would look nice spaced in front of tubes and between tubes and transformer.

@noromance  I believe much of the benefit of removing the cover is thought to be the prevention of resonance within. May be off on this.
