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.

Good stuff whart. All my speakers are dipoles (original Quads, Magneplanars, Eminent Technology LFT's), and I have been dealing with their backwave for years. But imo that wave is of less concern that is the vibration coming up into a turntable from below, the very low frequencies. That is true even if the table is not just out-of-line with the speaker sound, but even in a different room from them. A Minus K is on my to-buy list!
Fun to reread this old thread from 2017. After all that, I ended up with the slate-plinthed 401 on springs. The whole lot on 3" thick maple across concrete blocks.
The Apollo Wt2se or the Wt-1 wall mounted turntable shelf. The 2se has 2 shelves, in the event you want to place a phono preamp/sut below turntable. The wt-1 is a single shelf, of which I own, silver with oak shelf. They are both absolutely built like tanks.
