Tonearm mount to the plinth vs arm board vs rotating arm board vs isolated tower

The ''compounds similar to paint'' as well ''the isolation'' will not do.
There are many kinds of isolations as well many kinds of paint. 
Problem of notions without boundary conditions are the same as
sets theoretic  problem of extension. ''Set of all sets '' is example of
paradoxes  in the set theory. One need to somehow determine what 
one is talking about, Otherwise quantifier ''all '' can imply the whole 
universe + the added parallel one.

Huh? What the ding dong? 😳 When I use the word isolation I’m referring to the only real kind of isolation. If you’re still unsure what I mean let’s see a show of hands. 

Have you guys ever seen Halcro’s photos of the interior of his Halcro preamplifier? Something like that in black.

Geoffkat, I have oil + spike isolation in my Kuzma and pneumatic
feet isolation  under my Technics SP 10 with Obsidian plinth. In addition to mentioned  Kuzma isolation I have sand filled  base plate which is isolated with 3 spikes from the rack. Which one would you
call ''real'' ? 

^^^^
The oil is real
The spikes are real.
The pneumatic feet are real.
The sand filled base plate is real.

The end objective result for all of this paraphernalia.....is fake,
an illusion, not real, and it is limited only by ones imagination.

For this reason, anyone that holds "rigid" to certain principles in this Illusion of a hobby, lives, IMO, inside a box, with defined borders.
