See my response to mcondo and his thread "May not work.."
The balanced output on the SA-11 is already wired backwards!
If you switch the wires between pins 2 and 3 at one end of a balanced interconnect you will simply invert the polarity of the connected component. The "pros" do it all the time.
Of course, you can't just switch the wires in an unbalanced RCA cable, as you would "ground out" the signal.
My preamp only accepts unbalanced inputs, so I can't connect a balanced input directly.
What I would like to do is create a cable with a normal RCA connector at one end and an XLR balanced connector at the other end.
The RCA plug would be wired normally, the ground wire at the XLR end would be connected to pin 1 (ground), and the "hot" wire would go to pin 2 of the XLR. (Confusing, I know, but pin 2 of the Marantz is actually the inverted output!)
I would leave pin 3 (non-inverted) floating.
Since the balanced output voltage of the Marantz is exactly twice the unbalanced output voltage, My theory is that by connecting the two outputs to separate preamp inputs that I could invert polarity by simply switching between the two inputs!
