Best location setup of turntable


I have a pair of Tyler Taylo 7U speakers, Thorens TD145MKii, ClearAudio Microbasic phono preamp, and 55W Chinese built tube amp.
What would be a good (or best) location of the turntable?
Currently it is sitting on the bare wood floor in between an audio rack and the right speaker in my living room (20x25). The distance to the rack is about 3" and to the right speaker is about 10".

I tried to sit the turntable on top of the audio rack, but the vibration is much worse than just let it sitting on the bare floor. I tried to put the turntable on top of a sandbag, but it did not help much to reduce the rambling/distortion (or whatever you call) when the volume goes of 12 o'clock.

Any suggestion?
Would isolator help? What kind isolator would be good (Well under $100)?

Thanks for your opinion in advance.

An inexpensive pneumatic isolation system can be made by using a bicylce tire tube (depending on size of your tt an 18x1.5 or 20x1.5) and plywood board (1" or 3/4" and big enough to fit under your tt). Place the tube on your current stand-shelf, the pywood on top of it and the tt on the plywood. Inflate the tube just enough to raise the tt - don't over-inflate. A short straw or tube placed between tube and shelf will prevent a resonant air pocket forming in center area of tube.
