Floor spikes for speakers?

If nobody minds I’d like to, sort of, hijack this thread. What about spikes going into Black Diamond Racing discs on a wooden second floor?

I have a 100+ pound integrated amp, a streamer and a turntable on a Quadraspire bamboo shelved rack. 
If the recommendation is for some kind of separation between the floor and the rack what should I get?  I have, and love, IsoAcoustic footers on my Sonus faber Serafinos but I don’t think those will work under my rack. 
I appreciate your thoughts.

Oops. I meant to say the apes are on my equipment rack. 

Let’s try this one more time.  Not “apes” but “spikes.”

Like others have said, what’s under your wood floor is important.  The idea of isolation is to keep the vibrations in check. In my case, there’s plywood under my wood floors, so the vibrations just rumble through the floor.  If you have concrete under your floors The Isoacoustics Gaia’s work great. I’m not familiar with Black Diamond Racing Disks, but if they’re really hard and you don’t have carpet and pad, they should help with your apes. 😉

Thanks, curousjim. I have hardwood floors. I don’t know what’s under it, probably plywood. It’s an upstairs room in a typical late ‘80s house. 
 

The discs are very hard metal. I don’t have carpet or padding in the room. 
 

So, do you think I’m ok?  Should I consider more isolation under the rack?  What else should I try, if anything?

Thanks, again
