I had tried damping previous the result was much the same except for the reduction in amplitude at all frequencies. A minor change in geometric shape was the fix. A change of the reflective angle between the two surfaces. Tom
Nobody promised you a rose garden. If it (damping) was that easy everyone could do it. For one thing damping - like isolation - is an art. Take tube dampers, for example. While most of them look they would be a good idea, and many are very clever, they actually hurt the sound. The elastomer rings, the braided copper Swiss ones, the ebony ones. Almost everyone single one of them! Only one type of tube damper actually improves the sound.
Check out Marigo VTS Dots sometime, tiny little constrained layer dampers for all manner of things like capacitors, speaker diaphragms, speaker frames, component chassis, electron tubes, even larger dots for walls and windows. The most common Marigo dot size is 1/8" diameter. Hel-loo!
Damping, like isolation - It’s a science AND an art. Rome wasn’t built in a day. That’s why it’s important to damp the top plate of an isolation device but damp it the right way. There are plenty of wrong ways to damp it or to over damp it. The same thing goes for the way the component is interfaced to the iso stand and how the iso stand is interfaced to the floor or rack. The materials and shapes are critical. Everything is critical. My advice is don’t be an isolation hater. Be an isolation lover.
