DAC break-in question

Someone needs to explain the science behind electronic components needing to be “broken in.” I’m not denying that the phenomenon exists, I just don’t understand the science. 

There is some science and physics behind the break-in of electronics, but it has been taken way too far by people not understanding how minor it is and the reality. You do not need to break-in a component before listening, that's silly. Just plug the damn thing in and enjoy it. You must have the full circuit complete to break-in anything in the system as the circuit needs to be complete. Stop overthinking this, just play it and it will break-in with normal use. Don't expect some magical change.

I agree. In my experience if I hated how a cable or a component sounded right out of the gate no amount of break in could help. 

I am a true believer in “break in”. And you’re going to love that DAC! I had that in my second system and was blown away at the jump in performance when adding this to my system. What a great little DAC. Nothing comes close in that price range and even doubling the price nothing touches it imho. Enjoy!

Interesting. I can absolutely attest that my new BHK pre to my new Focal Clears required significant burn in before I enjoyed the sound.
