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.

@slaw your knowledge was very helpful in setting up my spring platform. I also utilized a lot of info from @geoffkait and others. There was much good info on the isolation thread a while back, and I appreciate you contributing to it.

My point in saying you need to drink less coffee or get laid, was that you’ve been popping into posts like this and laying out some knowledge, then getting upset that people aren’t instantly acknowledging your brilliance and jumping up and doing exactly what you say.
It’s not like you came over to my house and set things up. You shared info. Good info. But I still gathered other info, selected materials, made plans, built and adjusted my platform on my own. You’re acting like you did all this for me and I’m ungrateful. I acknowledge your help. And I appreciate it, as I’ve said before. But you need to stop acting like you are the grand master of isolation and we all need to hang on your every word and offer endless flowing praise at every opportunity.
If you keep that up, you’ll be know for being a-- rather than a knowledgeable member whose advice is sought.
@toddverrone,

Apparently, most view me as "an a--’ anyway, so I have nothing to lose? If you are really being honest, you view me this way, so don’t try and say, some may view me this way in the future. When I post, I come from a position of confidence by way of my own personal issues that I’ve had ongoing and found effective ways of dealing with. Your position started from a point of view you chose not to be honest about. Get real, dude!

I think my passion is greater than most that would lead some as yourself to feel this way.

The fact is/was, you were never grateful, until I brought this fact up.

Let’s get to the topic at hand. Your post to noromance reads like you are an authority on wall mount systems? Are you? Have you ever used one? If so, what meaningful recommendations are/can you pass on to noromance?

Let’s start here, alright?
Right, cement floors actually don't buy you that much since the entire structure of the house or whatever is moving right along with the surface of the Earth. And since the Earth's surface is moving like a wave on the ocean there are six count em! directions that vibration can travel. 
"With a wall mount system comes other problems...". Absolutely correct. I have used one with great success and also experienced horrible failure in two different houses. The latter was due to excessive vibration transmitted through the walls even though the wall mounted was secured firmly to the home’s support studs.

Following eliminate of vibration from external sources comes the frontier of draining and eliminating vibration and resonance produced by and within the turntable rig itself. This requires a completely different approach IME. "Soft isolation" approaches trap these vibrations and resonances within the component by eliminating the earth vibration ground. Need an approach that wicks away the vibration/resonance from the TT rig and then dissipates it.
