VPI TNT HRX table - what tonearms?


I just bought, but have not yet picked up, a VPI TNT HRX turntable, which comes with a VPI JMW 12.5 tonearm. I also have a Graham 2.2 arm and a SME IV arm. Assuming I had the proper armboards, would either of these be superior to the JMW? Would other tonearms be superior to the JMW with this table?

Stick with your 12.5 arm. It is v good.

I used to own the 12.5 with tnt5 hr, then moved to hrx with 12.6. I much preferred the 12.5. Damping trough is required imo.
The best Performance from a TNT I ever listened to, was such a unit with a ET2 linear Arm.
suttlaw,

How would you compare the TNT to your Cosmos? What was your reason for changing? What arm and cartridge did you use on the Cosmos?
