Vibration control inside a cabinet

Vibration control inside a cabinet

For placing an amp and a CD player inside a built in cabinet, what would be the best way to control vibrations: do I want some kind of isolation platform (actual brand suggestions would be appreciated), or something more like Herbie’s Tenderfeet? Or both?

Thanks!

Don’t go buying expensive audiofool stuff.
Just get some Sorbothane feet or pads on ebay, pick your size.

HRS Nimbus couplers and vibration dampers
i use them on a NAIM Unitiserve inside a cabinet..
works wonders !!
HRS is solid engineering

Sorbothane will give you isolation to around 10Hz---not low enough imo. Get a set of roller bearings (Ingress Engineering in Canada has the best deal on them) and some of Geoff's springs for isolation to 3Hz.

There are different densities of Sorbothane, the soft one will get down to 5hz but one needs to wrap it in Gladwrap before putting it under heavy equipment, otherwise it will spread over time.
I measured and listened  to both densities with a rare Shure frequency response test record under a non suspended turntable and the soft 10hz they sell on ebay, measured and sounded like it isolated just as good as the super-soft one. I say go the one on the eBay link I posted.

Innocent question: if Sorbothane is really so great an isolator why don’t the big boys at LIGO use Sorbothane? Obviously something’s wrong somewhere. Now, it’s possible that in some density Sorbothane might, emphasis on the word "might", be used as a constrained layer damper. But there are better materials for that application. I suspect Sorbothane is best relegated to running shoes as it apparently is a decent shock absorber. Which as I pointed out before actually makes it a poor isolator. Besides Sorbothane sounds well, funky. It’s not open and natural sounding like competent isolation devices. As LIGO found out after 20 years of isolation system development, there’s really no substitute for good old mass-on-spring techniques. Besides mass on spring devices routinely get down to 3 Hz performance and can be as low as below 1 Hz. Accept no substitutes. Finally the suggestion that Sorbothane can isolate down to 5 Hz is patently absurd since nothing can provide 100% isolation at 5Hz. Isolation is always a low pass filter. Of Sorbothane could isolate to 5 Hz LIGO would be using it.
