I went buy the dealer yesterday who had the SF Amati Anniversario speakers hooked up to : C500 p, pair of MC501's, MCD500. The room has now been sound treated since my last visit . These speakers sound superb and at the price he is selling them for which is half off of list someone here should buy them. The speakers look brand new, I did not see a mark on them. If anyone wants the contact infomation PM me.
