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?

The false notion of isolation? Are you out of mind?

Dive weights. 👨‍🚀 Give me a freakin break! I already know what you’re going to say, “It sounds fabulous!”

Knowledge. That’s what’s left after you forgot whatever it was you supposedly learned in school.

"....You can spend money and buy stuff but I recommend that you first try as many freebies as you can. That way you actually learn something. I started 30 years ago with phone books...."

I experimented with a dictionary before investing in scuba dive weights. I credit you with that idea from your Home Theater post.
I want to be clear, I'm not saying all or even any of these things are the way to go. I'm saying trying them is an experience that will help you learn to evaluate and select the really good stuff. 

Very little of what's out there is sophisticated, in that the properties are inherent in the material. That would be something like the carbon fiber and resin material in BDR Shelf and Cones. Inherently dense, very stiff, and highly damped. Its very rare to find something so across the board excellent as this. More often its combinations of compromised materials. VPI laminates acrylic and aluminum, for example, and lots of people laminate wood, or combine metals and elastomers. All they are really doing is what I did with my rack- combining different flawed materials in an intelligent mix that combines the best of each in a way that balances out or covers up each others weaknesses.

What I'm really saying is this is something everyone can learn to do. 
millercarbon, I guess you did the best you could do with what you have. You cannot be penalized for that. As McMurphy in One Flew Over the Cuckoo’s Nest sarcastically says to the inmates after he was unable to lift the 300 lb water cooler, At least I tried.  🤗
