1+ pragmas, digital volumes that are dithered are significantly better but still I leave all my digital equipment at 90% plus. Digital metering is a big plus in this regard. You can see where you are. In the analog world you just want to match volumes so you do not get a big surprise when you switch sources. Most modern preamps are hard to overload so I would try to keep them as high as possible matching volume to the lowest output source at it max volume.
For people who do not have digital metering there is a device called the Audiophillio that is a USB to SPDIF converter that controls digital volume with loss of bits. Very cool device.
