Killer deal.  
SF cosmetics on this their top tier line is as good as money can buy.  Tasteful, not gaudy.  Got to admit the Italians know art!    
I don't know how much double carton would cost.  Wonder if Sumiko would help find cartons?  It would take considerable time to properly pack these.  But you'd find a buyer quicker (obviously) if you could ship.  
Maybe packing on a pallet is ideal...but someone I know who ships speakers a lot said one trucker removed the pallet to increase room on his truck, resulting in damaged speakers...but if they are properly insured maybe the risk is worth it.
