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.

Since your table is obviously not subject to footfalls. I suggest you might want to consider what I have done, which is to use a Brightstar Audio isolation platform, which is basically a sandbox. I believe that may really help in your situation.

I also use a Target wall mount platform for isolation from the floor to support my Garrard 401, which has a heavy plinth of MDF, and is clad in solid Purpleheart, the face being 1" thick, side and top panels between 5/16" and 1/2" thick, and is coupled to the Brightstar with Edensound Bear Paws, which are 3" X 3" solid brass footers, and weigh 6 lbs. each.

This has worked well for me. This may have been mentioned in this thread already, but adding dampening (weight) to your support table may also help. 

Best of luck, regards,
Dan

Noromance, I hope I am not pointing out the obvious here, but the slate, by itself, won't isolate your 401/plinth from your existing table (if I'm understanding this right, not knowing if the slate will be on the top of the plinth, or under it). Isolation from the table is the key to success.

If you would, please report the outcome, for we of curious minds.

Dan
