Balanced connection from pre-amp to amp--Need help

I was hoping to get advice from the knowledgeable audiogon folks about making a balanced connection between my pre-amp and amplifier. I have a Marantz reference SC-11 pre-amp and Pass Labs amp. Marantz designates Pin 3 as the Hot (+) pin and pin 2 is the (-) pain. On the Pass labs amp pin 2 is the Hot (+) pin. I believe that Pin 1 is the Ground pin on both components. Can I connect the 2 components using XLR cable or am I better off using single ended RCA connections?
