LM4562 in and running. Merci bien, Matthieu! :up:

Sounding good but I want to give them a good break-in before having a proper listening session. What's the accepted technique? Is it OK just to leave a test CD on repeat with the amp turned off (or even disconnected...)? 😕

Op-amps don't need any break-in. The only thing that will need a proper break-in session are new capacitors. Break-in on anything else is a bunk myth or someone "perceiving" it sounds better because they read it online somewhere! LOL!

But likewise ... 2 thumbs up on the LM4562 ... EXCELLENT little chip!

I was wondering whether I'd get that response or "just listen to music and let them burn in naturally over time". 😀

Hypothetically speaking, if such a thing as opamp burn-in/break-in were to exist, what would be the answer? For the minimal effort, negligible cost and lack of downsides, I think it's worth leaving it playing for a bit just in case there is any advantage to be had by letting components burn in/break in/settle in/marinate.
