Maple platform under turntable, How thick?

All right. Thank you everyone. I will try Mapleshade 4" with their footers and will have brass cones for comparizon.
Over $200 for a piece of wood, oh, beg your pardon, air-dried hand-selected Amish craftsmen made piece of wood.

Granite...
Would look like kind of cemetery.
To clarify one thing. The woofers of my speakers are way above the floor level, and I get least vibration near the floor so all of my equipment is right down there.

Do I want to couple or decouple? You mentioned cones and bearings. What about Walker things, you know, those three massive cones going into led-filled discs and two more discs on top?

Right. Stanwal, thank you. There is virtually no vibration coming from the floor so it seems that both coupling and decoupling should work. I think, I'll try brass cones first.
I wonder if anyone tried platforms made of other wood, say, oak, cherry, spruce, ebony etc. How about 5" thick snakewood or ironwood platform?

Anyone used Polycrystal amp stand under turntable or tape deck?

Thank you. But I want Amish dried air made! Oops. I mean air dried Amish made.
I'll take a look at Tony's.

Since I am going to keep the platform under the deck on the floor, I think I will need either metal or possibly carbon fiber cones or maybe Boston Audio tuneblocks though I will try Mapleshade cork/rubber things too. I will go with either 4" thick maple from Mapleshade or 3" thick from Timbernation. And I will use Nottingham supplied platform for my Nakamichi deck with Polycrystal cones under it.
I am ready to sacrifice some warmth in sound for better dynamics though I won't tolerate any ringing.
