Albert Porters after market panzerholz plinths

I am very curious about plinths. I have an SP-10 MkII. It has the Obsidian plinth. I have mounted a Basis Vector arm. I have my table mounted on an older target wall mount stand. I removed the standard mdf shelf. I purchase threaded isoblocks from Mapleshade that replace the target spikes. On top of that I have a large 3 inch maple butcher block platform.

I am thinking about other plinths although is is difficult to know if it will make an improvement. I feel pretty confident it would sound different, but that is not necessarily better. I am going to at least experiment with Stillpoints and Walker cones under the Obsidian plinth.

If all the plinth alternatives were not so expensive I would be jumping into experimenting. My prior table was a Basis 2000/Graham 2.0. Moving to the SP-10/Vector was a big step up.

I appreciate all the good comments. My current plinth is the SH-10B3. I do have some Stillpoints on the way as well as Walker Valid points and Mapleshade triple points to try under my current plinth.
I suppose my thoughts are that any of the alternate plinths to be consider (aside from nude) are custom built products. So however I might arrive at a decision on which alternate plinth to try, it amounts to a leap of faith on a non-returnable product..So the opinions of those you trust who have walked the same path are valuable to consider. Thanks
