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.
