Maple platform under turntable, How thick?

I use four inch thick kiln dried Mapleshade platform on islocks under my clear auido Chapion ll table on a four inch thick four self Mapleshade stand with great results. The turn table itself weighs eighty pounds. Kiln dreid maple is soft and to me gives a very good sound. In my experiences I get a very open, authoritive deep rich sound. As stated by Stanwal, tweaks are not a one thing fit all. I also agree with Thorman about the brass cones. I use Bearpaws and Mapleshade.

Sorry, about my statement. Mapleshade platforms are air dried, not kiln dried.

On an Ariston tt, I have used 2-inch maple from Mapleshade with their rubber/cork/rubber footers to good effect on wood racks. On amplifiers I believe maple from Mapleshade(air dried) sounds better than butcher block maple. I have 4-inch maple from Mapleshade(which is supposed to sound better than 2-inch), but I haven't tried it on my turntable. Someone suggested trying maple blocks(I think he said Mapleshade has some, although I haven't seen it in their catalog) as a cheap way to try maple(maybe with isonodes under the maple?). As for other materials, I have used myrtle blocks with isonodes with good results on an early Nuforce amp.

Best you not entertain the half measures being suggested. The serious audiophile would go directly to an electron microscope table. These can be had for about $100,000. They will tell all that you are serious. Many years ago I visited someone who had such a table. He was so proud of it. I could not tell it made an difference. He was shocked.

I was happy with my a la Mapleshade 4" maple block on cork/rubber pads, untill I decided to try (based on A-gon thread) aluminum top plate on sandbox. Bunch of transistor heat radiators are bolted to the bottom of 3/4" anodized aluminum plate and submerged into 30 kg box of sand - all unwanted vibration are completely sunken through the huge contact surface and died out naturally in the sand . The whole thing is supported by 6 big and thick sorbotane pucks - look at the sorbotane site how to calculate the optimal geometry of the sorbotane pads to minimize natural frequency of the whole assembly.
I got much jucier sound combined with ink-black background comparing with the maple platform - I guess I'm done with isolation platform.
