The merits of slate plinths or not

Hi. Well, i have a lenco 78 that i refurbished and placed in a birchply/mdf plinth. Prior to this turntable i was using a systemdek table with a profile arm. I am using the origin silver mk3 with a denon 103 cartridge with the lenco. I find it to be very dynamic, good in speed, musical, natural and detailed. All in all i am very happy and satisfied. I would like to hear some dialog on whether slate would be superior to the wood plinth i am using. If someone through experience thinks they know what slate "sounds" like i would like to hear from them. I would especially like to hear from people who have tried slate plinths and have gone back to wood or some other tables. Slate is sediment compressed. If anyone has gone from a highmass wood plinth to a slate plinth , with everything else in the system remaining the same and preferred the slate, can you tell me what the improvements were and was the difference minute or quite significant. I have talked to people who have done some comparisons but havent been totally persuaded by their tests as it seems it wasnt a very controlled comparison.
