You need three Quad 303s or six Quad IIs, basically one channel per ESL-57.

You need a 3-way splitter cable, 4-pin DIN plugs at all four ends. Dave at Flashback Sales will make one for you.

Very good. The 303 schematic is available in the Downloads section (303 Service Manual). Pin 1 is L, pin 3 is R, pin 2 ad shield are ground. But don't trust me, check the manual.

A better description is ofcourse.

3 din connectors parallel connected to cinch.

I don't really see how that's better than providing the pin numbers, but YMMV.
