The right footing for a turntable

I had a VPI Hw-19 that I modded and tweaked a lot over the years, including the platform and supports. A few years ago I bought a Hanss T-30. I can divide the tweaks I did with the VPI into what still works, and what is no longer needed. What works: a support in the basement, under the player. No more skipping when I jump on the wood floor. A very solid granite rack. What is no longer needed: a sand box plus some air damping under the player.

Yes. Basement for me too. It sounds so much better than upstairs. 

Setting aside the suggestions to anchor the table to bedrock, as a newb, I would appreciate some commentary on my current setup and whether I should employ some tweaks to optimize it. 

My system is in the basement  - wall to wall carpet over concrete slab floor.  All of my system components are housed in a Salamander Synergy 303 cabinet - the combined weight of the cabinet and equipment (including TT) is about 200lbs.

The TT is a Music Hall MMF 9.1, which has a freestanding motor and sits on three conical, adjustable feet that come to a very sharp point.  The TT feet sit directly on the top of the Salamander Cabinet.

I cannot discern any obvious issues due to vibration transmission, but that does not mean there is no impact on TT performance / SQ.  Any recommendations on inexpensive tweaks to (hopefully) improve isolation / SQ enhancement.  Drilling to the center of the earth is out of the question (for now).

I'd be tempted to sit the TT on a stack of blocks with a paving slab on top. Those audio cabinets are full of hinges and chipboard!
