Default "Zen I / V Converter / buffer b1" make dac/preamp


do you know if it is possible to make / calculate a "Zen I / V Converter / buffer b1" ie, a two apareil?

and therefore have less of component and in particular comdansateur on the signal path.

So put it directly dac / preamp, a power amplifier?

this is a good voice? or am I wrong?

thank you in advance for your response

I'm not exactly sure what you are asking about, but it sounds to me like it might be something similar to this circuit recently published by Thorsten Loesch (alias, Kuei Yang Wang) over at diyhifi.org. See his post of Dec. 14th @ 1:44AM in the hyperlinked thread for the concept schematic. It's very much like Nelson's Zen I/V and B1 merged together, except that it features a folded-cascode (which eliminates the absolute necessity of the Zen I/V coupling capacitors) and a complementary output buffer.
