Turntable on suspended floor - shelf or braces?

My setup is on a suspended floor over a crawl space.

I'm about to finally buy a turntable (Rega RP6 or RP8) and am going to have to to address the bouncy floor. I set up an old Thorens just to try it out and there is a severe foot-fall issues (who knows how bad other vibration will be).

Looking for suggestions on whether I would be better off to put the new deck on a wall shelf, or if I were to reinforce the floor itself?

The floor is over a crawl space with a few feet between the joists and the dirt, so I could easily install 3 or 4 jack-type supports that would bond the floor to the ground.

Does anyone have experience doing this? Would I be better off with a supported floor, or a wall shelf?

Thanks - djm

My effective inexpensive solution for a suspended turntable (B&O) was to place cryogenically treated tempered steel isolation springs (Machina Dynamica Cryo Baby Promethean Mini-isolators) between the maple board the turntable rests upon and the horizontal top furniture shelf beneath.
For further vibration control, a VibraBlock Damper rests on the horizontal top furniture shelf.
As mentioned by Peterayer above, the sound is upgraded to a surprisingly impressive degree with appropriate isolation.
My turntable is protected down to about 3 Hz which is incredible for the low cost of the setup. When Godzilla next stalks the earth my vinyl won't miss a beat.
