Talking about counterweight, I would take the Michell Counterweight. I use it in a Rega P7 and Rega P9 and the final results, in my opinion, are much better than using the Rega´s tungsten model.
Thank you HBA.
I have heard many people talk about the Michell weight.
Some of the weights I have been considering:
Deepgroove weight (same type as the ISOweight, underhung circular)
Rega tungsten (excluded due to low weight)
This is really cool looking, like a spaceship from starwars
The original weight, and the tungsten upgrade weight from Rega are both circular with a centered hole.
The ISOweight and the deepgroove are both circular, buth with the hole towards the outer edge so that the center of gravity (?) is lowered.
The Michell has the weight underhung and a bit stretched to the sides, not shure what the effect of that is.
And finally the groovetracer has the weight(s) underhung and far out on the sides.
Geometry and physics.....
Oops, not my strong side I'm afraid...
But I'm confused about why these weights can make a difference.
I have been told that the closer the weight is to the pivot point, the better.
Ok, so a heavier weight takes care of that. (Why it is so, I still don't know)
The underhung weights seem to be a good idea, at least if it is put on a unipivot bearing arm. But for the rigid type of pivot/bearing in a Rega arm, why does it matter? ..or does it matter?`
I don't need a scale on the weight, like the Michell has. I own a Pro-Ject Measure-it digital weight. (So the tweak of setting the Rega adjustment to max can be done to check it out)
Also I'm not too happy about replacing the end stub on my RB700.
If I may skip the stress on the bearings needed to remove the old stub, I will. So the weights fitting the original end stub is preferred.
Looking forward to a good discussion about this, and the help to make my choice.
(Couterweight is not my third upgrade, as you might have guessed. But it might be my fourth)
