That is impossible. When you use the Balanced Output, both CS43131 are used for the balanced output. That means there is nothing left to feed the 3.5mm Output.looking forward on this. can I use the unbalanced and balanced output simultaneously on different earphones?
And the other way around. If you would use one CS43131 for the 3.5mm, there would be only one left for the 4.4mm which needs two.
So its not possible, the DAC would need 3xCS43131 with independent clocks and power supplies.
Its much easier and probably cheaper to just get two DAWN PRO^^ i use two DAWN PRO when i watch movies together with my wife. We both use open back Headphones (HD 490 Pro) and both are connected, via balanced, to an DAWN PRO.
That way we can talk naturally (thanks to zero isolation of the headphone) to each other and both watch the movie in the volume we like
