No worry. You should not have to rewire the XLR interconnects. My AV7005 is connected to a Gemstone amp using the XLR interconnects and standard balanced cables. Despite what the manual indicates, the PIN arraingment is 'standard' US configuration. To ensure this, you can check the labels on your amp pins. There is a discussion on this in the Marantz AV7005 thread over at the AVS forum.
