As posted before, unless the DAC or player has TWO 3 pin XLR analog audio outputs, all you will get will be unbalanced. A very few portable players (Pioneer 30R is one) have balanced out via a 2.5mm (NOT the usual 3.5mm) output jacks. And of course for balanced listening your headphone cord needs to have either twin 3 pin XLR male plugs, a 4 pin male XLR plug or a 4 pole 2.5mm jack plug.
You seem obsessed with balanced output. As I posted before, that is the LAST step and by itself is no guarantee of improved audio quality. Basically it is designed to eliminate hum caused by earth loops, something which is highly unlikely in battery operated portables. The difference between the audio quality of balanced vs unbalanced is not dramatic and will only be observed with the best gear and certainly not in items you have described.
