Tonearm Heavy Nuts

[JPK]

I recently became aware of heavy nuts for tonearm mounting. I saw one advertised for an ADC arm, then ran across the following link;

I'm wondering if they're worth using? If so, why don't we see more of them?
I know (additional) mass is generally good, but could using one cause any problems?

Thanks,

It would certainly cause problems on a suspended deck.

These seemed to be more prevalent with the old Japanese arms, the nut on my Lustre is very heavy indeed. I guess this just faded away when many arms stopped using the nut mounting arrangement and the lightweight plinth thing started to really take off.

AT 280lbs I've been called a heavy nut, but it's never helped my listening enjoyment. My Dr. definitely thinks that extra mass isn't good.

That seems ironic? I read somewhere that the heavy nuts were designed to improve lightweight tables? Sometimes I wonder which direction we're moving?

I'm thinking of one for an older deck I'm restoring. Machining cost may be prohibitive though, I'm wondering if they have to be threaded or just a weight on the post between arm-board and existing nut would do the trick?
