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

Chak, To your knowledge, is Toho still in the business of selling those accessories? The Torqueo stuff is beautiful (like a seashell, apparently) but not as substantial as Toho’s.

@lewm
No, not anymore, they are gone.
Toho also made their strange looking tonearm with bamboo arm wand (it’s on the same picture with cast-iron bases).

What weight did your granite base come in at?

The base weighs 18 lbs (8.1 Kg)......

But a SOLID GRANITE CRADLE, whilst not as heavy as cast
metal.....was GOOD ENOUGH and relatively affordable

Really - mines 68kg, and utilises SPZ which dissipates any energy between 4 and 100hz internally at a molecular level, but is completely rigid.

Granite rings like a bell due to its crystalline structure. I would not use it in a turntable.

Nice story....🤗
Unfortunately....a fairytale 🤥
Not only will 4Hz go straight through your plinth...but every frequency from 1Hz-10Hz will do likewise (watch the Mark Doehmann video again).
My turntable however, sits on a HERZAN ACTIVE ISOLATION STAND which cancels all vibrations from 0.5Hz-100Hz.

Can you please explain its crystalline structure which enables this?
Is it similar to bronze or CAST-IRON which are in fact used for bells?
Should you perhaps inform Toho who foolishly made their TURNTABLE CRADLES from cast-iron....🤔

And if you really believe that 'tapping' a material to see if it 'rings' is the criterion for turntable design.....I look forward to your new plinth made of plasticine to support your platter made of styrofoam 😝
