Dedicated Stand for a Turntable ? Opinions.

Springy floors are tough. Maybe you should look at getting the spring out of the floor. Some more support between the joists, perhaps?

All wood frame houses have some spring action going. What I tried to say is that they are not made of concrete.
Floor in general, is in good shape. I put two layers of 3\4inch. plywood and finish it with hardwood floor.
I am looking for the best way to reduce interaction between floor and tt .

.... is that any turntable benefits from a solid, unmoving stance that is unperturbed by the environment it is in physical contact with. Below is a link to a photo of my current dedicated turntable stand.

This rack is a massive and rigid floor standing affair. It stands on the springy floor of an upstairs flat. There is no problem with footfall in this instance for a couple of reasons. 1) layout of the floor joists versus traffic patterns. 2) Floor joists are springs and act like them. Any spring can be adjusted for oscillation frequency by altering the amount of load placed on it. Higher spring loading = lower oscillation frequency. So I've weighed down the rack with a heavy slate plinth beneath the Td124 seen in the photo. The result is a placid turntable stand that sounds very good.

I have also used wall racks with success. Keep in mind that even though we don't see them, the structures holding up our racks and stands, floor joists beneath plywood, or load bearing 2x4 studs behind sheetrock become a significant extension of our mountings and contribute their own sonic signature.

At this point in time, even though I'm on a springy upstairs floor, I'm in favor of the floor standing "mass loaded" dedicated turntable stand.

Nice stand Steve. Very clean lines. Cool, solid joints.
I was just wondering, what kind of wood did you use for lags ? Looks like an walnut but I think you used a stain in order to match double ply. shelves. Also did you use a solid peace of wood or a sandwich two pieces for lags?
Looks like two to me.
What is a total weight of a stand?
Thanks for a link and cool pics.
