Energy damping or energy transfer?


Are there some generally accepted guidelines about which components to isolate (in terms of vibration damping) and which components to "couple" to the rack (which is also coupled to the floor)?

I freely admit to being clueless here (I'm still trying to get my head around cables and power cords), but it seems like the "brass spikes" guys are saying something completely different from the Vibrapod-type isolation guys.

Given what they're asking for these products and the potential number of components involved, it's like considering a major component upgrade.

Also, has anyone noticed once a component is isolated/coupled that either the interconnect or power cord is affected? Thanks. If this has been kicked to death in the past, just posting a link would be great.

Generally it is better to dampen vibrations. Most often blu-tak does the job. Sometimes a very flappy & resonant speaker enclosure (poor design) may benefit from anchoring or coupling it to the stand and the floor as this may reduce certain resonances or shift them below the audible range.
Cbrentc,

LOL ....your thoughts make me think that someone should extend their noise cancelling headphones into a device to cancel vibrations....all you need is a 3 axis accelerometer tied to the device you want to stabilize and then a negative feedback loop to a 3 axis vibration servo that actively vibrates the device in the opposite way and cancels out all vibration ...airborne or otherwise.....this is the kind of stuff which is used in inertial guidance systems...it would not be cheap! (Of course the device would need its own internal damping...but this is common already)

Worth a patent perhaps?
