should I suspend a floor-standing turntable?

..just remembered....another excellent way to support the turntable is to attach the stand to the wall using turnbuckles (at Home Depot). Tighten the rig and you'll be amazed at how much better things sound.

Stringreen, this certainly has not been my experience and neither is hanging from the ceiling. In one home I had earth below where the turntable was and used a three inch pipe with a screwable plate that really did help and in another house built on a slab putting the turntable on the floor was quite good. Elsewhere sheer mass was the answer. I once heard a system in Chicago where the guy got curbstones under his turntable. Each weighed about three hundred pounds.

Wall shelf worked great for me in Germany.
Germans don't use drywall .

Thank you all for your responses. I've decided to purchase a 1'' wood block from Timbernation and am currently looking into footers that are good for carpets.

Schubert, I can see where that would make a big difference. Where do they run piping and wiring? Or is it just plastering over the walling?
