Vibration control on brick floors?

[loki1957]

My listening room has a brick floor on a concrete slab. The walls are 6 inches thick covered with thick plaster. The ceiling is pine wood with logs. It's an adobe house in Santa Fe. My question is does it pay to use any kind of vibration devices? I use 2 Michael Green equipment racks and the amps are currently sitting on the floor. I have a bunch of brass cones under the equipment but I can't hear any difference of improvement with out them. Any suggestions?

You can try various gaia acoustics footers under your speakers which certainly help with decoupled timber floors and may be an option.

there are other manufacturers of similar products but unfortunately I have no direct experience with.

Given your homes construction, I might try something more absorbtive vs brass cones that couple. Possibly try Symposium shelfs or Grand Prix Audio stands (they have sorbothane in a few locations). Years ago I used to have a Arcici suspense rack, everything was suspended on a air bladder, another possibility. It's hard to know for sure unless you try it.

I don’t know about needing vibration devices but if the dimensions are good the construction of your space is wonderful. Vibration control typically means dampening, wether it’s active or passive and whatever the means. You can always change the character of your sound by sticking something under your rack or equipment, you decide if it’s for the better or it‘s worse. Easy and cheap way to experiment and understand what you need is place a 3” x 3” tile of hardwood between your rack and floor and hear what happens. This is resonance interference, for dampening you can buy a set of sorbothane discs and place them under the feet of your equipment. IMO if you’re looking to spend serious money on this, upgrade the actual components first.

Vibration control typically means dampening

Yes but not with these ,Finite element
These decouple but dont dampen at all , i have the classic standard under my speakers, dampening usually means reduced dynamics / energy loss
The ceraball should work fine under lighter gear , but to work optimally they need a certain amount of weight on them
Plus you don t have the hassle you have with moving things on spikes , spikes are hopelessly unpractical under speakers when moving them around.
Built quality is top notch.

The speakers im currently designing are much smaller floorstanders and will get the ceraball footers

Thanks for the suggestions. Does anyone have any experience with ebony pucks or cones.

...and isolation. Both, when narrow-band (the usual situation) can be harmful and subjectively deaden the sound, wide-band is another story but harder to achieve.
