Hey First of all, I am not sure if there is a specific term for a non-discrete circuit. Doing some googling, most people refer to it as "integrated", but I never heard the term used for DAC's. Is a fully discrete circuit always better than a hybrid or non-discrete one? As far as I understood, in DAC's non-discrete circuits, they generally use OP-Amps. For instance, if one dac uses a non-discrete output stage and the other a fully discrete one, with everything else exactly the same, would the discrete one sound better? Or is a full discrete circuit just a means to an end, a way for designers to squeeze out the maximum performance of a DAC chip? Or a necessity for some DAC designs? Would love to hear your opinions.
