Turntable isolation...

The Vibraplane is a spring system too, you know, air being a compressible fluid, so an air spring has a spring rate just like a steel spring and the reason it’s so stable is because it doesn’t isolate in at least some of the rotational directions, it is not free to move easily in those directions, not sure about the twist direction, but probably not. My platform went a lot lower - as low as 0.5 Hz vs 3 Hz for Vibraplane and mine isolated in all 6 - count em - directions. It was also a spring system.

I've used a MANA Acoustics wall mount for years. In spite of various high priced isolation devices which have made a significant difference, there's the weak link: the wall. I've gone over in my mind for years different ways to rebuild the wall. What keeps holding me back is the time it would take me to construct verses the time without my system providing so much joy.
I recently came across Geoffkait's springs and ordered a couple of sets. I put a set of four under my Symposium Ultra that supports a VPI Classic 3 Sig. SE w/ a set of EdenSound Terrastone footers coupled to a set of Stillpoints Ultra SS. I also put a set of four of his cryo'd springs under a BDR platform, in my MANA set-up that supports my EAR 834P w/ Stillpoints minis.
What a difference! First, there is almost no vibration felt through these components now when I touch them. The overall sound: no harshness at all, bass + midbass is so much more resolving. The best under $100.00 I've spent lately, by far.
I have researched the MinusK units and still think at some point they may be an option when I do finally rebuild my supporting wall. I think it would be wise to consult with them on your specific TT and make a custom unit. I'm no longer in any hurry however, to take on the project. Thanks Geoffkait!

Thanks for the report Slaw. Which of Geoff's springs did you get?

Keep the turntable out of "line of sight" from the speakers!

Geoff, would you draw any comparisons with your springs & Max's Seismic Pods...??
