Graham Phantom Supreme?

Rockitman, Wrm57, the 10" arm wand was - as the 12" arm wand - Graham's reaction to market request. Indeed you will have a hard time mounting a 9" Phantom (or any other 9" pivot) when the platter diameter exceeds 320 mm or when using an outer ring on the platter. Whether Clearaudio, VPI in specific or others - the 10" is the way to go when using the outer ring anyway. But pay attention to the off-set.

so there is no advantage with longer arms ? I though longer arms had lower tracking error ? That's why the Gradenzza is 12" the Durand Telos is 12" ect. ? Help to understand...

Rockitman, please - don't get me wrong.
Aside from increased effective mass a longer effective length version is always superior in terms of tangential error and sensibility to SRA/VTA variation due to the inevitable hills and valley on every LP.

It is in specific here - with the Graham Phantom and it's armwands of 9", 10" and 12" resulting effective length.
As I said: look careful to the off-set of the headshell mounting area.
It is correct only for the original 9" version.
That's why the 9" version here is the "best".
Usually I would always vote and go for the 12" version - but not here.

Size is not everything. Short done right can have some advantages ....

I wonder if the new adjustable jig is configured for each tonearm length ? The plastic alignment plate is now fully ajustable so that no matter the cart height, you can get the alignment plate parallel like a record surface. Also using the ring, wavy records are not an issue. 99% of mine are flat using the ring. I suppose with the greater effective mass, there will be better performance with low compliance carts like the Allnic Puritas (Which I am considering).
