High or low-mass record weights/clamps: which is best?

Blimey Mark that's nearly 10:1

That's a veritable black hole of increased gravitational force.

I can't know but I am expecting that internally it's more thoroughly engineered Clearaudio Clever Clamp sort of arrangement. I've always meant to try one of these but never got around to it.

That looks interesting. Is it not limited in that it can only apply as much force as can be created by the downward flexion of the record into the recess. I assume the tabs on the inside flex upward to provide a resistive force against the spindle when it is pressed into place. But with the tabs effectively going into the spindle perpendicular to the record surface how much downwards force can they transmit?

It looks clever in that it no doubt requires quite a pull to remove it, but how much downwards force can it impart. It's really no different to the star-fangled nut used in the headset of my mountain bike forks- the difference is, that requires loading up with a allen key to provide any downwards pull.

Functionally that seems to do what the Michel clamp does through a different mechanism. Mark's is different again.

I think you have to twist it to remove it - will make one and investigate.

I have a Souther Clever Clamp which in use, even on my Heybrook TT's.
I like what it does to the sound most of the time, doesn't load the bearing and applies a moderate amount of pressure when usen with a flexible record mat, like a linn felt mat.

It is sold by Clearaudio, but is actually labeled Souther.

Ps it does not require twisting to mount/unmount.

Hmm...today I made myself one of those Souther clamps (laser cut acrylic) and it basically just uses friction to grip the spindle - so the pressure it is capable of exerting depends on the compliance of the four plastic fingers. It is a very low mass design though.

It doesn't really apply much pressure though; although it does grip the spindle quite firmly.

Now that looks proper funky. Can't say i'm surprised it doesn't actually provide any useful downwards force though.

Yup, no doubt Funky, with a capital 'F'! How useful is it, though? :)

Marco.

useful to prove the concept doesn't actually provide clamping force like a weight or Marks new clamp does.
