Another “How to choose an arm” question


I currently have a Sota Saphire running an SAEC We317 arm (221mm spindle to pivot and 12 mm overhang).

That is running a Garrott Bros p77i, but I have been looking at some LOMC cartridges, as well as SoundSmith LO-MI, AT ART, etc.

How is one supposed to determine their current arm is good or not?

It sounds fine and I would think that the knife edge design is not prone to a lot of wear.
However it was recommend that I upgrade the arm… But how would I know “to what”, and how would I know if the upgrade is worthwhile?

I was looking at some DD tables to have a more expanded choice of arms that can be mounted, as the Sota is a bit restrictive in that regard. That is still on the cards as a possibility… however assuming that the Sota is a keeper, then how do I determine the arm’s adequacy, being “fit for purpose”?

@rauliruegas , Raul, I do not think the Reeds will fit on a Sota. Arms with VTA towers push the horizontal bearing to the out side edge of the tonearm well and the counter weight hits the outside edge before the arm gets to the run out groove. You would have to cut the plinth away for it to work.

and the Eclipse upgrade that mijostyn posted.

mijostyn for what you posted you have very low knowledge level on the SAEC tonearm quality performance. Of course that if the 317 colorations is what the op  likes then is up to him.

@mijostyn , got it but the Reed could work for the second tonearm that needs an external arm pod.

@rauliruegas , That is true, it is surface mounts and could be mounted on anything you can get to the right distance. Why on gods green earth would you ever consider an external arm pod? The tonearm and the platter have to be rigidly mounted on the same very stiff non resonant structure.                                              Where am I wrong about the SEAC? Is it lighter than I think it is? It looks like a boat anchor. But, I do not know the exact spec so in reality you are right. HOWEVER, the arms I mentioned are a lot lighter and more flexible. (notice, I said nothing about sound) I know you like the SME V so don't screw this up. 

 

Another long-term Sapphire owner here, and I'm not sure why @rauliruegas is universally down on uni-pivot tonearms.  My Graham Phantom is certainly an ideal match for my rig and has been bullet-proof reliable as well as easily repeatable for VTA on-the-fly adjustments.  The 9" Supreme version I selected was a drop-in retrofit with a new Sota composite arm board.  Set-up was a snap, too.

I also took advantage of Sota's Series V suspension and bearing/platter upgrade at the same time and couldn't be happier with the overall package.  It's everything I expected in my upgrade from my old Magnepan Unitrac and more versatile by a wide margin.

Hope this helps you in your search and happy listening!
