An arm to live with for years to come

I am guessing that you want the liquid midrange that the unipivots can give, and the solid bass response and detail of the SME gimbal-bearing type arms. Usually you have to give up one to get the other. Except if you get an OL arm like the Silver, Encounter, or Illustrious. They are known to give liquid mids like the best unipivots, and the deep bass and detail of the best gimbal-bearing arms. They also have great musicality and are not analytical sounding. I would strongly recommend considering them, as I think they will do better than either of the arms you listed, and cost less too.

like albert, i've owned and used this tt, too. maybe a decade ago, or more. best combination i tried was the (long-out-of-producttion) grado arm with the highest-end grado cartridge then available. weird lookin' but on the path towards nirvana.

i would avoid the SME arms (which i've also owned), because of thier bloated bass. but, as always, YMMV.

The SMEV is not an ideal match for your table. The bass is not accurate or wasnt in my set up. I switched to a Graham with very good results. The Naim aro would also work well, much better than its plain construction would suggest and that would be my choice.

I'd go with the JMW 10 or 10.5 but with the caveat that they don't handle edge warps with much grace, at least with the Grados (I have a Reference too, the original version).Then I'd ditch the clamp in favor of a Ringmat. This ridiculous-looking thing (which isn't supposed to work well with VPI TTs) really did wonders for my early model TNT. At least see if you can borrow one and try it.

The Walker unit undoubtedly bests the earlier model VPI motor controllers, but I would question whether it beats the SDS, which is the best favor I ever did for my TNT.
