HRS Isolation damping plates

Ghost, if the plates make a difference. . . try also some lowly material. . . Lead shot I already spoke about. . . but a 50Lbs bag of rice , pinto beans, or sand. . . may do the dampening trick as much on top of a component.

50lbs of DS will work.

I just tried these and they improved things a lot when I play loud music with low bass. I tried "lowly material" but it just moved the problem around.

My electronics are between the speakers (bad idea, but I have no alternative). As a result, the top panels of all my components vibrated quite a bit when I played it loud, especially when the song had low bass. The Lyngdorf 2200 is known to respond well to SOTA vibration control. Stillpoints helped it a lot so I figured these damping plates might be a win. They were.

Adding one HRS damping plate reduced the vibration quite a bit. One more helped but its not as dramatic as the first one. Lowly material doesn't reduce the vibration nearly as much as these plates. Sound quality improvement correlated with the reduction in vibration observed.

IMHO some of these newer vibration control products (Stillpoints, Cerapucks, HRS stuff) have some physics backing them up. Look at how Stillpoints work - its a long way from a tiptoe. These plates have some interesting combination of high compliance and the right amount of mass to damp out the vibration. I suppose if you could find material with the right compliance you could duplicate what they are doing. But life is short and they aren't that expensive.........

Every time HRS damping plates were listed on Audiogon, I missed the opportunity to buy them. In the interim, I purchased damping disks from Herbie's and they do work as advertised. I would however like to try the HRS damping plates to see if there's a difference so if anyone's selling, let me know.

SYMPOIUM Fat Patz work very very well they dont overdamp witch is great. Work great on transformers of tube amps and solid state.
