Upgrade Suggestions

I have a VPI Aries 3 with SDS, ring clamp 10.5 Arm and a Dyna 20XL cart. The Phono Pre is a BAT VK-P10 and the amp is a Woo Audio WA 5 through Paradigm speakers. I listen to mostly jazz and vocal music.

I love my system, but am getting a big tax return, and have the upgrade bug. My thoughts are either a new cart or a rim drive motor, either the Teres or the VPI.

Any thoughts would be appreciated, thanks.
