Looking for a great arm that is low maintenence

Nrchy, most good arms require careful setup but none that I know of (including the unusual Souther linear arm) require any maintenance.

I have a SOTA Cosmos also. I have replaced the SME IV with the Graham 2.2 and I am delighted I did. Overall, the Graham sound more transparent--no heaviness in the bass--and livelier. It also offers more adjustments and execute them better than the SME.

I have had a long look at the Wheaton Triplanar. Great construction. It sounds excellent in my friend's system but in my limited exposure to it, it was not as ergonomic as the Graham. So I selected the latter. Though there are too many variables to make a valid comparison, I felt that my system with the Graham sounds better than his with the Triplanar. Finally, I like the fact that Graham has been consistently improving their arms over the years and offered reasonable upgrades to their customers.

If you are like me, no matter which arm you eventually buy, you are going to have the nagging feeling that the one you did not get might be better. These are great arms that will all do well on the SOTA. Any one of them will give you great sound. Just pick one and enjoy!

Nrchy, I had both the SME and the Graham on my SOTA for several months--they use the same SOTA board!--so I had time to compare them with a variety of cartridges, though not the ZYX.

My experience was that both arms work extremely well with the SOTA but the Graham was slightly superior to the SME in most respects: better sound (bass), better adjustments (VTA on the fly) and greater ease of use.

I sold the SME and kept the Graham.
