Twindac+ and Django (BD-Design)

By having a transformer as suggested, you caNot achieve a stable
impedance at the DAC chip output, as the impedance changes with different
turn ratios.

But as I said before: If you load the dac output trafo only with the django, then the reflected input impedance also changes with the volume (tap) selection of the django. Unless you have an additional load on the dac trafo which had be smaller than the reflected input impedance from the django (which is usually quite high if you have a valve grid at the amps input stage. But I think you could provide that low load also if you have just one trafo.
Mirko, are you the designer of the twindac?
