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.
get a wall mountable shelf for it. They can be found for $100, or a lot less if you're handy.
I second Bdgregory. I use a Target. If you're not particularly handy and it takes more than $100 to do the job right, you will find that it's worth it.
Unless you want to play with various suspension systems, a wall mount as Bdgregory suggests may be the easiest answer. Hopefully, owners of Thorens tables will add their experiences.

The second issue after what to place it on is where in the room to locate your table. Keep in mind the tt/arm/stylus are designed to be sensitive to very small vibrations - this means both mechanical (addressed by wall mounting) and acoustical. If you own or can borrow a CD player and a disc with bass test tones, than can help. Play a segment with frequencies of 120 cycles and below at slightly louder levels than you may listen at. Move around the room to every location when you might like to place your table. Lean forward to place your head right over where the platter/arm would be positioned. Listen for excess bass energy. You should discover a wide variety in bass loading from one position to another. Being close to your walls, the amount of energy may surprise you. For best performance, you will want to locate your table where the bass loading is minimal. Most likely this will be away from any of your corners.

Good luck.
ditto Bd.
Unless you have your turntable on a concrete cellar floor,you really need to get it on the wall..Nothing has to be fancy..just pick up a couple nice wall brakets and make your own wallshelf..pretty easy to hang wherever you want..Works like a charm........
If I hung my TT on the LR or FR wall my wife would ..fill in the blank.. me

Yes a TT mounted on a wallshelf is the best likely way of isolating your TT. I would say if you cannot mount it on a wall because of construction or esthetic reasons than try an ikea lack table they are light ridget while warding off unwanted vibration because of there light composite wood structure,Walmart and Target sell such a table to under another name.
I filled in the blank and imagine you smiling...
You mean, it's not on the wall yet??
I learned that two small racks next to each other was better than one tall one. I played test tones as Pryso mentioned and found the place with the lowest volume tones. It turned out to be along a side wall, with spikes through the carpet and pad to the concrete floor. I avoided the wall because traffic from above and behind created vibrations. I also shielded the TT from any direct sound from the speaker by using the second rack and a MDF board. You'll have to experiment and see what works. A combination of spikes, Sorbothane and Herbie's dots are what I use. Have fun, and enjoy!
I've seen many wall mounts ad for turntable, but did not know whether they would work so well, as noted.
However, my current system is in main living room and I don't think my wife would allow me to hang the rack on the wall.
How about some of those isolation pads? Would they work as good as wall mount rack?
Many thanks for you thought.
I am considering relocating my turntable closer to my speakers. Right now it is on the opposite wall, but it is nearly a 40 foot run of speaker cable, so I have to go cheap on the cable (monoprice 12 gage cable). By moving it closer I could use better quality 8 to 10 cable (Kimber - black and gray braided cable).

I have concrete floors and plan on leaving it on a floorstanding rack, since very little if any floor vibration will transfer to the stand...but by moving it closer to the speakers the base may cause more vibration. So it's a trade off, better cable but closer to the speakers for shorter cable run and better quality cable.

What do you all think? What would you do?
check out Machina Dynamic Promethean base. This would allow you to put it back on top of the rack
Many good advice.
I thought a pillow cover filled with sand would be as good an isolation device than any other, but I guess I was not right?
Aagin, my living room is wood floor. Among isolation platform (by nimbus or similar), wall mount rack (by Target or similar), and isolation pads, which would be best, per performance/price wise?
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.
the tt should be on a heavy solid rack and then isolated from the top shelf. if you have a wood floor you place the rack 4-6 inches from the wall and using a wood braket attach the top or second shelf to the wall. both the wall and floor vibrate at opisite times so they will cancil each other out. there are many isolation shelves out there use the heaviest you can afford. the weight helps to cut dowm sound wave vibration and isolaters stop the vibration from the other equipment on the rack. i do not understand the wall shelf. the walls receive the largest amount of air wave vibration, plus even the best wall shelf is FLIMSY at best. carter9000 move that table behind the speaker using the rack system described, you want it as close as you can get to phono and line amps. VIBRATION is what it is all about, everthing in music is created and destroyed by vibration, the entire high end is based on controling vibration.
Another room, on an inexpensive computer printer table! If any part of the sound can get to the cartridge, you will have colored the sound. Same goes for tube amplifiers, if the sound can get to the tubes. So, try out the relocation to see if the sound is 'cleaner'.
How do you guys feel about the mounting of a 'table on different surfaces depending on if it is suspended or not?
I don't understand the objection to the wall mount, but perhaps your wife might not object to suspending the turntable from the ceiling using thin picture wire. I use 4 such wires to suspend an MDF board (easily leveled, using turnbuckles on the wires. The turntable (an Alexandria MkIV) is placed on the board. The effect is quite striking - it seems as if the turntable is suspended in air.
By locating the platform near a wall I keep it from floating all over the place by installing two small springs horizontally on the board edge to allow the platform to gentle rest against the wall.
the only vibration that can reach that setup is airborne and the turntable is at least 15 feet from the speakers. The suspending guy wires effectively serve as very low frequency pass filters.
