I would almost bet that David has the only 2 in existence. It does have an uncanny resemblance to the AF3
Perhaps the much anticipated AF Zero will be fashioned after the AS. Of all the tables David has in his museum the AS with the Neumann DST cartridge lit my ears up like none of the others
Probably they made more, I only came across two in my travels. I look and search every time we're there . The square shape of the AF3 has the same origin, RX-5000 & RX-1500 of the 70's...
