Vibration isolation or absorption?

Robert,

You are indeed playing semantic games, and are clearly biased given that you have related products for sale. Also, please stop with the straw men.

Spikes couple components to whatever they sit on, while spring/damper devices can come very close to decoupling the same components. That difference that can be very important, and your attempts to conflate them, presumably for marketing purposes, are obvious. 

The fact that there is not 100% decoupling is irrelevant, and for what should be obvious reasons.

Max once said “ Any material or device you put under any piece of equipment will change the sound”. Sometimes for the better, sometimes not.

Some things I have found to work:

Townshend Platforms, Ingress cup and balls, slate, very slightly inflated tyre inner tubes, springs, a combination of these.

Do you know the acoustical tiles people put in their ceilings, and on the wall. They’re about three or four dollars for one square foot piece.

These are excellent absorption panels and they fit real nicely underneath certain speakers and other components. And what’s really cool about them is that you can easily slide the component around, and the speakers can slide a around to if the footprint isn’t too large.

How’s that for solving the vibration problem?

Dubious. 🤣

absolute mechanical isolation and decoupling cannot exist in the presence of gravity

You throw this out there to further your self-serving post, intimating that because absolute decoupling is impossible, your way is the only way.

Absolute decoupling is not achievable and not necessary! A resonant frequency of the decoupling device at about 3 to 5Hz will prevent transmission of any musical sound. The rumblings from a nearby volcano might get past the device but then I think you may have bigger problems 🙄

Spikes couple and couple well to a surface and will efficiently transmit vibration in both directions.
