jeez, run it through the floor into the basement?
My other hobby (one of them anyway) is amateur astronomy. There are discussion groups devoted to things like building your own observatory, etc. One of the common discussions is how to build a stable pier to mount telescopes on - any vibration is very noticable through a scope at moderate to high power.

If you built his stand and extended the legs to the basement, you'd end up with an upside-down pendulum (despite the sand in the legs). It would tend to exaggerate any vibration from bumps and would take awhile to dampen out, although properly done by decoupling from the first floor, it would at least isolate the turntable from floor vibrations as people walk around.

People who do telescope piers often have foundations for them that are reinforced poured concrete blocks or slabs that are about 1-2 meters in all three dimensions, coupled to steel pipe or poured concrete posts. Here are some examples:

If you go up a whole floor, it gets even more complicated... :)

I really like the appearance of these clear turntables. They looks absolutely stunning. Here's another-- http://www.musicalfidelity.com/mf/en/Products/Turntable

Kach22i...does that stand have some sort of gravel in it for vibration control?
The story is in the link. He took PVC tubes, capped the bottoms, filled them with sand and sealed the top with clear acrylic resin. I guess if you were doing that, you could cap it with colored glass beads or sea shells or what ever turned you on.

I'd like to know if the paint ever came off the PVC, or if a special paint was used. It must be in the article, I just don't recall at the moment.

Alright, let's say I don't want my turntable in the backyard......... :)

Do you have any links for sprung (wood) floor reinforcement?

I enjoyed the links, I realize putting my turntable on the fireplace apron is just my personal compromise on the topic.
Buy or build a wall rack.
