OPA1612 or OPA1656

[Acapella]

Hello together,

i want to put one of the mentioned OP Amps in my amp.

Which of the two mentioned OP Amps (OPA1612 or OPA1656) is the better one, in a scientific point of view.
I don't care about listening tests or something else, just want to use the technical better one in my amp.

Thanks in advance.

Best regards!

It's not that simple, I'm afraid. It will depend on driving impedance and load impedance, as well as how the feedback is configured.

With that responsiveness cherry on top - this is certainly my way to go forward. Just looking for a DAC+preamp that has a configurable sub out and dirac that matches well with this now. You'll be wanting a miniDSP flex then :D

There's a long thread about op-amp rolling somewhere here, too.

Fosi Audio V3 op-amp rolling, has anyone tried it? Snake oil? Or are there actual differences?

Disclaimer: I'm fairly new here and with so many forums, it wasn't easy to decide which one to post this... If this is not the best one please let me know or (if you're a mod) feel free to move it. TL;DR: I've recently order a Fosi V3 (should get it next week or so). I'm not sure I'll keep it...
