Nottingham resonance control

I am trying to figure out how to do away with those rubber feet, both under the table and the motor. Or at least to greatly improve the table-platform interface.
Currently, my Spacedeck sits on a 3" maple block which is right on the hardwood floor with Boston Audio tuneblocks under it. No Nottingham platform. My speakers are on Boston Audio tuneblocks for speakers. I have very little floor vibration even at high volume level.
I was thinking about Walker resonance control discs or Steelpoints. Steelpoints are very expensive, Walker discs are $50 each. I would need six - three for the table and three for the motor.
What are your thoughts and experience?
Oh, yes, I am also using Boston Audio Mat-1.

Tubehead, I've been eyeing the Segue ISO myself, for use with my Townshend Rock Elite table. But then there's also the Townshend Seismic Pod, which is also a spring isolator. Decisions, decisions!

Tubehead21, thank you, you add Symposium as yet one more possibility.

Inna, I recently came across some data which suggests that Rosewood is superior to Baltic birch plywood, and to slate, but still much inferior to Panzerholz. I still like the idea of veneering Rosewood onto Panzerholz.

All depends on what you're trying to do. Baltic birch is valued for its stiffness, which in itself is quite a good isolation parameter. Other woods I suspect have varying degrees of anti vibration behavior and or stiffness and of course it depends a lot on the thickness of the wood. There are a lot of variables involved including beauty of the wood, no? If you want to go for the high density look get a hold of some iron wood.

'depends on what you are trying to do' is an excellent point. I advocate the approach of tuning the system and controlling the resonant energy not eliminating it altogether. Hard to accomplish and requires a lot of experimenting, including trying different woods. I would start with woods used for making instruments, ironwood is not one of them. Brazilian rosewood, spruce, cocobolo etc. In the end it might come down to personal preference, and that's good. For example, I like the sound that is deep and a little on the loose side but not much.
