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?

Hello again Suttlaw, a Trans-Fi Terminator linear tonearm easily surpassed a SME IV and Graham 1.5tc on my modified VPI TNT. I've corresponded with an HRX owner who experienced similar improvement replacing a VPI 12.5 arm. The stock tonearm mounting hole can be repurposed without modification.
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?
