Left and right XLR's are analog outputs, not digital outputs.Steve, that's of course true in nearly all cases. But not in this one. First, the P-03 is just a transport, and does not provide analog outputs. Second, if you look closely at the rear panel photo shown in the "gallery" here you'll see that the two XLR connectors are identified as L and R respectively, and are within the panel area that is identified as "digital out." Finally, corresponding L and R digital inputs are provided on the D-03 DAC, which is linked to by the "system" button on the P-03 page and is described as "combining two identical monaural D/A converter components into a one-piece body."
