Machina Dynamica under 'table?


I have checked the archives and found some good press on the Promethean isolation platform. Are there any new users or experience with it under a turntable? I have one arriving today to go under my Spacedeck which resides on a rack on a sprung floor. I am hoping this eliminates the remainder of floorborne vibrations that my existing Neuance/DH Cones didn't solve. And as a side note, I am expecting the sound to be improved too.

Any thoughts?

I tried one under my Acoustic Solid One. I can report that it's too compliant under a table that heavy and with an outboard motor. Despite Geoff's very helpful advice, it was nearly impossible to find a position for the springs that is both level and non-responsive to any vibration from the motor pod. I nearly lost my mind trying to make it work. YMMV with the Nottingham.

Note: I now use two maple blocks with 3 industrial McMaster-Carr air bladders between them, on Harry Weisfeld's recommendation. Works very, very well. They don't lose air either.

yep...get your deck off the floor rack and use
a wall mount

I used a Nimbus under my previous turntables to good effect. The improvement with the SOTA Cosmos, admittedly rather heavy for the Nimbus, was good, while the improvement with the Linn Sondek was stunning. I don't have experience with the Promethean, although it can take a lot more weight depending upon the springs used, so it's definitely worth a try. Microseismic very low frequency vibration is effectively dealt with on these devices. I use a Nimbus under my CD transport and wouldn't be without it.
