Final update. I just talked to my local dealer. He has been selling Sf for years, and cautioned me against buying something as old as the Futuras. He actually gave me a deal. He is going to sell me the Nova V speakers at the same price I was going to pay for the Futuras. He says he has the newer Amati speakers at home, and the Novas are so close to them that he would have bought Novas if they were available when he bought the Amatis.
The only downside is that I have to wait for the Nova V's to come in. Fingers crossed it won't be months.
