I would suggest waiting on any upgrades until after the CES in January. VPI will be coming out with a few upgrades for the Aries that are said to improve performance substantially. In particular, the platter/ring of the new TNT-HRX will be available for the Aries. VPI also mentioned plans to roll out an upgrade for the JMW and a new motor assembly for the Aries. The arm upgrade will, I think, be a new VTA adjustment device that will offer greater rigidity than the current one. The new motor assembly will apparently be oblong-shaped and will house both a motor and a flywheel (somewhat like the new motor on the HRX).
Lastly, I believe a new low-wattage motor is available from VPI. This motor produces less vibration than the current motor. It is my understanding that this new motor can be easily dropped into the current motor assembly.
