Gfloyd53, I'm the guy Raquel mentioned. I also had a VPI TNT 3.5 with the JMW-10 tonearm. I ran it with a van den Hul Frog for several years - until May, that is, when I swapped out the JMW-10/Frog for the SME IV and Dynavector XV-1s. The SME IV arm works perfectly with the turntable, and the sound of the new tonearm/cartridge combination significantly surpasses that of the JMW-10/Frog.
If VPI can get you an arm board for the Aries 2 that is machined to accept the SME IV, I would not have any reservation about going in that direction.
