European Vibraplane?

Yes, from the specs Minus K seems way beyond the competition. But I'm wondering if anyone has ever heard a difference between VP and MinusK (in a system with a serious bass capabilities of course...and probably with less than optimal floor, e.g. suspended).

Townshend Seismic Platform looks interesting, from UK.

It's an interesting question which iso platform is The Best since a lot of the "art" of isolation involves how the platform is supported, how the component is supported and, like you say, how bad the situation is to begin with. We do know that Earth crust motion, in and of itself, is sufficient to cause problems. Halcyonics, a Swiss German iso table, is interesting and there's always Newport Corp. and TMC. Myself, I like hardened steel springs and heavy masses.

IMO There is lots to learn about isolation for audio components ... from what i have seen/read these vibraplane type isolators only isolate in the vertical?!

There is only one device I know that will isolate in ALL 6 axes ..."vistek" will do this but they are stupid expensive!

when i was searching these were the top!

We discuss all the exotic options when most have their turntable sitting on spikes on a wobbly stand.

A single Vibraplane is a miracle under a turntable and very cost effective. Four Stillpoints Ultras is $900.00. You can purchase a used Vibraplane for that and pick up a cheap pump and be in business.

I don't know about Newport Corp. that Geoffkait mentions, but Vibraplane is a product of Kinetic Systems and is only one of several isolations stands they offer.

Here is specs on Vibraplane I purchased. Good numbers and good price.

Horizontal Natural Frequency 1.8 Hz

Isolation Efficiency @ 5 Hz 81%

Isolation Efficiency @ 10 Hz 95%

Net Load Capacity @ 80 psi 450 lbs.
