Technics SL-1700 feet

@nandric i don't want to impress anyone, but at least you should know that The AT-616 support from 10 to 60 kg, look here. 

These type of pneumatic footers can be placed not only under any turntable directly (or dac, cd player or whatever ) ... but also under heavy subwoofers if needed, or easily under some big butcher blocks even if you have more than one turntable on such block. 

The weight of turntable often vary because we're all using different plinth of different weight, some slate plinth are too heavy.   

these can placed under table or speakers for $19,  https://mnpctech.com/turntable-feet-replacement-isolation/turntable-vibration-isolation-pads-pack-of-four.html

Great Audio-Technica insulators in comparison @nandric :
AT-636 here
and more expensive AT-616 here

hope it will help to understand their entirely different structure 

Dear chakster , ''better than… relation'' can be endless , The
formula is R( a, b, c,... n). I was very glad to find the AT-636 
in order to substitute for the ''worthless'' original footers under
my Obsidian plinth. I am convinced that the sceptical review 
of the SP-10,mk2 with Obsidian plinth  was caused by those
worthless footers. I forget the price but those were not cheap.
Anyway  I don't need ''better kind''.
