Turntable - On the Wall or to the Floor?


I'm in the process of buying a new analog front end. It was recently recommended to me that I make every effort to put my turntable on a stand that's tied into my "real" wood suspended floor rather than put it on a wall.

I have a 1920 farm house and the floors are loose, wavy, and I can't find a level spot. I once tried my Billy Baggs stand with my old turntable setup and this was scary.

My walls are 2x6 and plaster. I was going to use a Target shelf that's secured to the studs. Doesn't this method also tie the TT to the floor since the studs and floor joists are tied? Any suggestions?

Just one more thought on wall mounting: if your floors are extremely bouncy, try to mount the shelf near a room corner.
The walls are very solid (1920), and the wall studs have really aged over the years...like drilling into hardwood. Then there's the plaster. I have a curio cabinet with light glass shelves on the other side of the wall. There are some tiny glass figurines on the shelf. When I open the cabinet door you can hear them rattle. However, not until I jump to about 6" off the floor can I hear anything...and I'm no lightweight.

My new concern is that the TT plus dampening slab will be heavier than the Target shelf can handle which is 88 lbs.
I have been to Timbernation's site, they're the ones who sell the Sandbox TT platform that I mentioned earlier.

I was thinking about using that platform but it's too much for the Target shelf. A maple shelf substituting for the target stock shelf may work if the combined weight is under the max. Or, I could use the Sanbox but would have to come up with my own wall mount design.

Thanks
SHIMS! We carpenters ALWAYS use wood SHIMS,
to say level out a floor for a wall for
studs, or to even out a space in between
the stud frame and the door frame to
make them level.
You can get these at Menards, H.Depot,
lowells, etc.
