Plinth to armboard interface Garrard 301 plinth

The best thing by far to use under a nice massive stiff table like yours is a set of Black Diamond Racing Cones screwed into Those Things screwed into the base. They are standard 1/4-20 threads making it easy to swap in case you want to compare and see just how much better they are than, well anything you care to try. It will look something like this

I've had good luck with my 6" layered MDF plinth, Solid Purpleheart slabs, using 1" face board, 3/8" Purpleheart top and side plates, for my Garrard 401/Denon 103R. Purpleheart arm board is solidly affixed to the plinth using stainless allen screws.

The whole assembly is around 70lbs. It has Edensound Bear Paw brass footers (@6 lbs. ea.) on a Brightstar Audio BigRock 2, sitting on a wall-mount stand. It has been very rewarding to listen to since I finished it a couple of years ago.

I believe you tried everything to say the simple cones are the best? 
But this is what everyone has by default, normally

Do you understand what is preumatic insulators such as AT616? 
I don't know about any similar product on the market

Even Raul has been using them under his subwoofers (good idea) where the cones are most common solution. 

Actually the cones are what we would like to replace with a better things such as Pneumatic AT616 or something different like Stillpoints for improvement. 


  

What do you mean, "the simple cones are the best?"
Where did you get that?

my temporary footer set up is a steal cone sitting in a brass disc with a dimple with some very thin (1/16") sorbothane pads under each brass disc. this has been good but not the best as it floats and may not be that stable specially if bumped. 

I've tried a  softer footer and I found the sound lost some focus, the cones seem best so far but i'd like a little more isolation if I can.

 thanks for the suggestions. I will look into the links. 

My footers sit on a 160lb, 4" thick granite slab. that sits on a three legged Lovan stand.  I have about all the mass I can take with out it going through the floor (ok exaggeration). 

I can not wall mount in my current condo-loft unfortunately but I'm in a steel and concrete building that's also diagonally braced for earth quake resistance so surprisingly stable.
