Support table or shelf for turntable


I was hoping to replace my oak table with either a wall mounted shelf of a heavy steel table.
The reason is that I am finding that the oak is picking up and transmitting vibrations to the turntable, a Garrard 401 in a birch ply plinth. I am hoping to move to a slate plinth and wanted to maximize the support strength and reduce feedback.
Here is a link to the shelf and here is a link to the table. Both examples of what I'm looking at.
Shelf would be mounted to concrete wall. Table would stand on concrete floor.
Thanks.

I'm just happy to see Michael Green's (Room Tune "guru") proposal of component "tuning" by constraining outer structures with spikes falling out of fashion. Wrongheaded then, wrongheaded now, wrongheaded forever! We want decoupling (isolation), not coupling, right?
I have to admit all this springs stuff has come as a bit of a surprise. Mr. Kait and Mr. Green appear to have some interesting online correspondence. And more interestingly, an interest in Peter Belt who I remember from the 80s. Indeed, I sat in on a few black foil triangle demos. 
A spring suspended platform isn't cumbersome at all if made well. Check out my system page. I think my platform looks rather nice. Even on a shelf on a concrete wall, there are seismic and airborne vibrations.
Todd, looks good. Does the table not roll away?! Might be more of a challenge with my 60 pound turntable!

noromance,
I love your Eico monoblocks! I just gave my daughter my Eico ST-40 integrated. However, not original so heavily modified.

Anyway, I'm moving towards the decoupling approach for my gear as mentioned by geoffkait and others. I've had tremendous success using decoupling springs with my subs to solve mechanical feedback issues through my turntable.
