European Vibraplane?

Looks like Newport is at the heart of those isolating platforms. They have their own technology:

As I understand it's active: there is a mechanical level sensor, coupled to a valve which controls the airflow to each isolator:

The performance plots show a good 2.5Hz resonant point.
If it's available in EU for the price they show, it'd be very attractive.

The "Drawings" tab explains it but should be probably viewed upside down.

A Newport engineer recommended these:

Very reasonably priced, but certainly not as efficient as the Vibraplane. They do have isolators with terrific vertical and horizontal isolation (1/1.5 Hz respectively), but the load required is just not practical for home audio application.

Then there is also this:

Those compact, low profile units would seem best for low shipping costs to EU.
Just put them under a steel ballast plate (obtained locally) to get the total load
close to the max. design load and that could be a very nice solution with a quiet
compressor. Has anyone tried these?

Peter,

If you're referring to the SLM series isolators from my first link, you only need a bicycle pump, not a compressor. The S-2000 series isolators need a minimum of 660 lbs to perform, so they are arguably not suited for home audio use...

The platform from my last link uses four isolators that Bydlo linked and looks like the equivalent to the Vibraplane and Minus-K, but the price is not listed.

Assuming the SLM series isolators do a decent job, they indeed might a pretty good deal and an alternative for those who can't afford a Vibraplane.
