contact the manufacturers

Ask CI and Rogue how their balanced signals are derived. Chances are, the DAC signal is actually taken balanced from the d/a converter. Doesn't matter if the CD player is balanced; that's digital. Most dac's produce a balanced signal and are converted to single-ended. I don't know why so many manufacturers waste the opportunity to pass a true balanced signal to the outputs.

A phono preamp can produce a balanced signal, but not many do and I doubt that yours does. It is probably derived from a phase splitter between the preamp single-ended outputs and the balanced outputs. In that case, the single-ended path with less processing will probably sound better.

The signal that is genuinely produced in a balanced fashion, most likely the DAC, is the one that should sound better, but one never knows for certain.

If the manufacturers won't divulge the information, you can always lift the lids and have a look around. Look for an opamp, which would comprise a phase splitter, near or wired to the XLR outputs.
