Vpi vs. TW Acustic

My analog rig consists of a VPI Aries I, Triplanar, and Benz LP. My SoCal dealer suggests the Grand Prix Monaco TT should be my next move. However I don't have that kind of moola lying around and just try finding a used one. It ain't happening. So, would the TW Raven One be a big improvement over the the Aries or too much of a sideways move? And without the opportunity to audition, too risky?
