The company I work for does pro audio gear, and having had a brief conversation with a couple of our engineers, their conclusion is that unless you're running REALLY long cables (from a few hundred feet to several miles) or in an extremely (electrically) noisy environment there's not really anything to be gained from using a data transformer on your digital outs, provided the circuit was properly designed in the first place. As to whether the Squeezebox circuit is properly designed or not, I can't say as we don't have one here to dissect, but such designs tend to be pretty cookie cutter for standard chip sets.

This is what I'm looking for. Can anyone comment on George's
speculation about transformers?
