Best Tonearm Match for Shelter 901


I remember reading here on Audigon that some of the "best" tonearms (Graham in particular) are not suited for use with the Shelter 901 or 501 cartridge -- for whatever reason.

If anyone has recommendations for what they consider the best tonearm for the Shelter(s), I'd love to know what those arms are and why they would be a good match.

Also, if you could expand on why certain arms may not work well with this cartridge type -- I'd like to learn.

I currently use the Shelter with a Linn Ittok tonearm with what seems like great success, however I am in the process of building a Teres and would like to purchase the best arm possible for that table.

Eminent Tech. ET2 and ET 2.5 arms are excellent arms.
Yes, they are slightly more involved in setting up but you get rewarded with the result.
As long as you have near by closet or room, you can set the pump outside of the listening room(longer the air tube, better it is). Stock ET pumps are not that noisy either even if you need to keep the pump in the listening room.
Once they are set up, my set up did not need much maintenance unless I move the turntable. Cartridge changing is a breeze due to removable arm tube.
If you can set up your own cartridge, you can set up this arm. When you are looking for one, make sure they are either stock or just have Wisa/Surge tank upgrade. Don't purchase one if they have too many DIY modifications.
I have heard from others that the new Kuzma Reference cartridge is actually a shelter 901 with the Kuzma label. Kuzma must then feel that this cartridge is a match for their arms which have about 12-12.5gr mass.
