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.

Really? First you have to control the magnetic flux surrounding your ears so that it is perfectly symmetrical. Take any headband and using silicone glue two one inch neodymium magnets right above your ears. Amazing. And you won't have to worry about dripping sweat on the record.

My MicroZOTL2 benefits greatly from damping.Isoacoustic footers helped and two pounds of weight on top changes the sound for the better in this lightweight component.I'm currently experimenting with materials and figuring out how to incorporate a damper that's not hideous.The bayberry jar candle works well,but looks ridiculous:-)

VPI and the small HRS also Symposium makes some great ones they are best less damping is always better.Dive weights is a big cheap joke.

@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.
