Turntable Setup advice requested


This is similar to a previous post of mine, but it is a different question.

Basis 1400
Rega 900 Arm
Benz Lo4 cartridge.

The turntable sits on a stand made up of approx 100 pounds of cement.
Three large Bolts are the stand's feet (and leveling device).
1/4 in. plexiglass dust cover sits on weatherstripping on the cement turntable stand.

The cement turntable stand sits on the floor in the basement, which is the "audio room"

Questions:

1)
Should I put "tiptoes" on the Bolt heads so the three "feet" of the cement turntable stand can punch through the carpet and padding to make contact with the concrete floor?

Or

Should I leave the "Bolt Heads" flat and let the carpet/padding do some "decoupling"?

2)
Since the Basis 1400 has no real suspension, should I buy a product (I'm sure one exists) that should go under the Basis tt's feet?

3)
Is my cement turntable stand a bad idea?
Is there a better approach?

Thanks,
Steve

Assuming that your table, arm and cartridge are set up correctly:

100 pounds of cement stores a lot of energy. With the bolt heads sitting on carpet, the carpet decouples the cement stand from the floor and this energy has no where to drain. Your turntable, having no suspension, becomes part of this energy block. The result is the turntable getting upset by the large amount of energy it cannot dissipate.

Suggest you experiment with a light weight but rigid stand with spikes or tip toes to pierce through the carpet. Then try using tip toes or sorbothane feet under the turntable to see which works best.
