I started the project with AK4490, and the digital part is fine, I have doubts about the analog output.
Firstly, I thought of using an OPA1611 in a simple differential configuration, and I obtain the following result through the simulation (images).
My question is: Can I get better results using only a discrete buffer, such as HDAM SA3?
* I prioritize fidelity, lowest distortion possible, without any coloration.
The impression I have, is that with discrete buffer gets better headroom values, but in compensation a lot more distortion than using opamp. Right?
