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?

Huh? Are you out of mind? Manufacturers have always (rpt always) been two paradigm shifts behind the power curve. Advanced audiophiles have always (rpt always) been the pioneers of this hobby. Manufacturers never got the memo for power cords, fuses, isolation or wire directionality. They’re too hyper focused on circuits. 👀 And perhaps too busy admiring their own handiwork to pay attention to what’s going on. This is the sort of debate that easily distinguishes the mid fi fanatics from the high end. A myth is as good as a mile.
There have been many ideas down through the ages for using things on tops of speaker cabinets and electronic equipment - e.g., the now defunct Tekna Sonic dampers, Totem Beaks, Super DH Cones, Brilliant Pebbles, Golden Sound’s Acoustic Discs, and stacking 4” ceramic plates on Small DH Cones. Not so obviously perhaps a spring-based isolation system under speakers and components kills two birds 🐦 🐦 with one stone - damping internal resonances and isolating from mechanical vibration - acoustic and structureborne.
Brass, another low end material. Not a big fan. They should call it Low Eden Sound. 🤗
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.  🤗
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.
