I was thinking to put a transformer at the input of the 6N6P-based stage, putting a low value resistor at the dac output, thus forcing it to work in current mode. Which transformer, among the Sowter or Lundhal models, does fit best for this kind of application?
Regards.

Which is the overall gain of your output stage? I also think that the gain can be controlled by inserting a resistor in parallel at the secondary of the output transformer. This way we obtain a lower output impedance as a plus... I'd also like to try the Buffalo dac in current source mode. I was thi...

Thank you for your answer.
Did you try to force the ES9018 into current source mode? And in the case, did you use a transformer?
Regards.

Re: Buffalo DAC output stage

Hello Nick, did you connect the outputs of the buffalo II directly to the grid of the 6N6P? Or did you use a series capacitor? Did you tune up the circuit? Regards. Alekos Leo, asked me about what I was doing with a output stage for a Buffalo DAC, so here is the simple as they come circuit I am usin...
