Hi,

I quiz the ultimate authority (Tom Cumberland) on this one.

His answer is . . .

"I would suggest that he try connecting the hot to pin 2 of the XLR and the ground to pin 3 without using pin 1. This will make the RCA look balanced to the balanced input of the A1400. He should also try plugging the AC power lines of the Denon and the A1400 into the same wall socket so that they have the same neutral and hot lines.
