How good is the Obsidian plinth of Technics SP10 ?

I recently got a TECHNICS SL-1000MK3D - SP10-MK3 SH-10B5 Plinth. and have just installed a Thales Simplicity II tonearm.  Surperb sounding table on my diy compression spring platform.  

  I feel there is nothing wrong with the plinth as its very well damped. The feet however, I feel they might be able to be inproved?

  How do you get the feet off the SH-10B5 plinth?   I have tried unscrew the feet, however they will not budge and I don't want to break them.

I used Stillpoint Ultra SS’s under the Technics mk3 plinth, by passing the feet. Results were poor.
Using the Mk3 feet was clearer sound, but a little bass heavy - more my rack than the Technics as when I transposed the technics onto the Granite/compressions spring stand - everything improved markedly.

Hi Lew

  Yes, that is the Thales tonearm.  

 The tonearms are easily swapped as you just remove the entire armboard by removing the 4 screws.

  Hi Kong.

  many many different plinth options for the technics. I am happy with the Technics mk3 plinth, however I do need to find out how to remove the feet safely.

  cheers

Hi Tellefsen

 Something is not quite right if you are getting feedback from your turntable at any volume.
  

  Stillpoint Utra's and V's work well in place of the stk feet.

as do these in the link.  value for money is excellent.

Hi dgarretson.

  agree in the overall improvement factor, my micro seiki cu-180 had a bigger improvement on my SP10mk3 than the Stillpoints.   
    However, the Technics sitting on a 4" piece of maple may not be doing the stk feet or Stillpoints any favours.
