If I may, i didn't want to create a whole debate and it seems to confuse people, in effect I was just pointing that the differential output of the DAC chip doesn't tell any info if the output of the unit is Balanced or not. In fact it doesn't matter either they use both output to create a symmetrical and impedance matched pair to ground (a balance signal). The unit is not a preamp, not an amp, it's the very first stage of the analog audio chain so if the output is balanced it's a balanced DAC. the differential output of a dac chip matters if you connect it to something after it with a differential input A balanced output is different and it's not less balanced or pseudo balanced, it's balanced, regardless if they use both output of the chip or one. We can debate if something is truely a balanced design if it has analog inputs and outputs, we can then debate if the signal stays symmetrical troughout, if a XLR connector has just been put there for convenience, etc. but in this case it's just an output. You may be interested to know if they indeed used both polarity inverted output of the chip or if they used used a switched capacitor but there is not one method that is less balanced than the other. It's the very begining of a chain in a balanced configuration, and this balanced signal in all case is being generated after the chip. I was just pointing out that checking if the chip has differential output is not the right argument to say this DAC is fully balanced. In fact it can only be fully balanced or not at all.
