VAS has his big VPI off-line, currently enjoying TW Acustic, using his collection of VPI Uni-Pivot Arm wands to demo cartridges with it. You could ask Steve Leung what he likes about it

I don’t see a dust cover.
Here's a Raven 2 in Canada, with extra parts for 2nd arm, links to reviews, might be a source to learn about them
