Like you said, the digital outs are for use with outboard DACs or receivers with built in DACs (3 different types of connections). The RCA analog outputs are standard, unbalanced and the XLR are balanced. If your Unico has XLR inputs, you could try connecting it that way to see if it sounds better than the RCA jacks. It should, but it depends on the design of the two pieces. If the circuitry isn't balanced, it may be a waste of time. XLR jacks don't necessarily mean that the circuitry is balanced.
