I would take the Sabrina over the Sonus Faber. I have heard the Sabrina and the Nova 3. The bass went deeper and had more texted/impact on the Sabrina and I put a lot of value on bass. The highs are about the same. The mids are a little different. The Nova 3 has a slight dip at 3k and I feel like the wilson have a slight peak at 3k I heard a touch of sibilants in the Wilson’s. After demoting both speakers (a few others too Kef R3, Cornwall IV, etc)I bought Revel 228be based on a demo of the 328be.
I can’t help with Vandersteen.
