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.
@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. 
Good DIY method.. Ordered custom sized steel plates (3.5" x 5.5" x .75"), spray painted matte black, and a layer of dampening material on the bottom, which controls resonance, and protects the component They make great weights to put on top of my dac.
