SF discontinued the Cremona line. Look for closeouts. They also show up used in good condition in the classifieds here. You *might* be able to score a pair domestically for $5K. They're worth saving up for and I'm with you about SF Cremonas vis-a-vis the B&Ws.
Here's an entirely different approach you might find attractive. It worked for me: A pair of Magneplanar 1.7s with one or two fast subwoofers to give you linear bass down to 40 Hz (or even below, depending on the sub). I liked Cremona Ms, couldn't afford them, got 1.7s and already had the subs. Couldn't be happier with my setup now.
